Production part

Production part

Description

The production part is a part roll and contains the relevant production data. This module is used to maintain production parts.

A new production part can be created in two ways:

1. From the input window of the parts master via menu item
2. New button in the editing / list window of the production part

If the production part is called up from the input window of the part master, the system first checks whether a roll of this type already exists and displays it if necessary. Otherwise a new production part is created and connected to the part master (only after saving). On the tab 'Production data' the data from the part master are taken over, which must be supplemented by the missing points.

With the second option, a new part master record is created for the production part when saving, which you should maintain afterwards.

A production part can be defined as a normal assembly (part has a bill of material and routing), factory assembly (part has no bill of material, only a routing), MRP assembly (the production part has its own MRP bill of material and is only defined from a logistics point of view) or engineering assembly (the part is not "seen" from a logistics point of view).

Fields

Field	Description
Production data
This is where the most important data on the production of a part are kept. Central here are the parts list and the work plan.
: number *	Production part number. This can be different from the part number in the part master. This is a mandatory field!
: Search terms	Search terms of the production part (see also menu "Specific search terms").
: Description *	Description text of the production role. This description can/should be different from the part master text in order to highlight production-specific characteristics. This is a mandatory field!
Part *	Reference to the part of the production part: the production part data is partly modelled as a role
: Operating assembly	Indication whether it is a production part that does not itself have/needs a bill of materials: these can be parts that are either only further refined by a work plan or parts whose material itself consists only of manual stock or of auxiliary or operating materials. This option is only useful for parts that are part of another BOM and therefore not a level 0 part. This information is particularly required for a part precalculation, as otherwise a production part without a BOM will lead to a termination there. This specification can only be set if no BOM or MRP BOM is specified.
: parts list	Reference to the parts list of the production part.
: Dispositive product structure	Description of dispositive assembly If a bill of material is linked in a production role and an entry exists in the MRP product structure, the specified part is "pushed" on the entry of the MRP product structure below the production part when the production bill of material is exploded. All parts which are specified in the bill of material item list on the purely MRP assembly are thus moved from higher-level bill of material levels below the new entry. Only one valid MRP product structure (MRP assembly) can be created. It is possible to assign a formula to individual entries. If the formulas are so different that only one valid MRP assembly is found for each purpose, multiple entries are also possible. Further technical information and instructions for creating an MRP assembly as a variant bill of material.
: : Constructive assembly	Identification whether the production part is generally to be managed in a parts list as a constructive assembly (constructive assembly). If a part is placed in a master BOM, this identifier is also transferred to the master BOM item. If you want to change these identifiers subsequently, you can do this via a special service of the parts usage module. This identifier cannot be set if a) the part is not a production part, b) the part has no BOM, or c) the part is managed as a stock item. If the part is a dispositive variant part to be produced without its own BOM (i.e. each sub-part has its own BOM), then only a warning is issued: in the course of a BOM explosion, any replaced sub-part would then be treated as a constructive assembly.
: Work plan	Reference to the work plan of the production part.
: Batch size	Quantity that is offered as a production quantity by default. For certain parts it is not worthwhile to manufacture them individually, as the set-up times would be too long. For this reason, several of some parts are always built at once. This lot size is entered in stock orders (warehouse orders) as a quantity proposal.
: Lead time	Rough lead time of the part in production. This should not be less than the sum of the lead times in the routing (after resolution). Serves as a first rough estimate for the production of the part without having exact knowledge of the work plan. In contrast to the replenishment time (see below), only the production time of the part itself is meant here - without its assemblies, i.e. also without the procurement time of sub-parts, which can be quite longer.
: : Determine maximum lead time from work sequences	The throughput times (days) are added from all work sequences of the work plan referenced on the production part. For conditional items, the longest lead time is used. After pressing this button, the calculated lead time is already entered in the field, but not automatically saved. This lead time is only a suggestion and must be confirmed by subsequently saving the production role. Attention: This button is only visible if the type of lead time is set to "Value".
: reloading time	The replenishment lead time is the lead time + the largest replenishment lead time of all disposable subparts of the first stage. Time required to manufacture the part, including replenishment times of all disposable subparts. Corresponds to the replenishment time of an ordered part (see also Lead time field).
: : Determine maximum replenishment time from all MRP subparts of the referenced BOM.	The replenishment lead time is the lead time + the largest replenishment lead time of all disposable subparts of the first stage. The longest replenishment lead time is determined from all MRP BOM sub-items of the BOM referenced at the production part and added to the own lead time. The batch size of the production part is used for the calculation. For conditional items, the item with the longest replenishment lead time is used. After pressing this button, the calculated replenishment time is already entered in the field, but not automatically saved. This replenishment time is only a suggestion and must be confirmed by subsequently saving the production role. Attention: This button is only visible if the type of replenishment time is set to "Value".
: : Planning supplement	Enables an additional buffer time to be defined for the backward date calculation if the procurement time is determined dynamically. An additional waiting time is defined for the part and the start date is shifted forward by the value.
: Logistics *	The logistics indicator. This field is only available for manufacturing services. This is a mandatory field!
Features
On the 'Characteristics' card, you can define characteristics for the production part. This list defines the material characteristics to be taken into account in production (e.g. proof on the working papers).
: Create	Create a new local attribute.
: Insert	Inserting a feature from the master list of features.
Remove	Remove the item selected in the list.
Costs
The 'Costs' card allows you to enter the material and wage costs.
: Cost categories	Indication of the cost element for posting the costs incurred in producing the part.
Material	Standard or even planned costs of the material used for the part.
: : Variable costs	Indication of the variable material costs for the part. The variable material costs can be displayed via the button can be edited on the left side.
: : Overhead costs	Indication of the overhead costs of the material used for the part. These could also have been stored in the client. The overhead costs can be displayed via the button can be edited on the left side.
: : Material Total	Summary of the variable and overhead costs of the material. The total material costs can be displayed by clicking on the button can be edited on the left side.
: : Allow zero material costs	This checkbox can only be selected if the material costs are zero. Normally, production parts without material costs are not recorded in the final costing. These are recorded as batch errors and can be displayed and corrected. If this checkbox is selected, the labour costs are posted in the final costing without generating a batch error. If the material price is conditional', the checkbox is automatically deactivated. Material or labour costs must be available, both cannot be zero and can be posted to the post-calculation without batch errors.
: Wage	Standard or planned costs of the production hours used for the part.
: : Variable set-up costs	Indication of the variable set-up costs. The variable setup costs can be displayed with the button can be edited on the left side.
: : Variable costs	Indication of the variable labour costs for the part. The variable labour costs can be entered via the button can be edited on the left side.
: : Overhead costs	Indication of the overhead costs of the production hours used for the part. These could also have been stored in the client. The overhead costs can be displayed via the button can be edited on the left side.
: : Total set-up costs	Indication of the set-up costs before the production of the part can be started. The set-up costs can be displayed via the button can be edited on the left side.
: : Total wages	Summary of the variable overhead and set-up costs of the wage. The total wage costs can be displayed with the button can be edited on the left side.
: : Allow wage costs to be zero	This checkbox can only be selected if the labour costs are zero. Normally, production parts without labour costs are not posted in the final costing. These are recorded as batch errors and can be displayed and corrected. If this checkbox is selected, the material costs are posted in the final costing without generating a batch error. If the wage price is conditional', then the checkbox is automatically deactivated. Material or labour costs must be available, both cannot be zero and can be posted to the post-calculation without batch errors.
: Sums	The bare sum of material and wage costs WITHOUT surcharges
: : marginal costs	Marginal cost is the sum of the variables wage and material costs. (Overhead costs are not included here).
: : Preliminary costing	Marginal cost is the sum of wage and material costs including overheads.
: : Production costs	The costs allocated to production overheads.
: : per date	Date of entry of the costs.
: : Test value	If the costs are conditional costs, attributes with test values can be added to the "Sum" group. These values are saved at the production part, so that all data do not have to be re-entered when called up again. Using the context menu, attributes can be inserted and removed, and automatically transferred from the part. In the event that the costs are variable costs, the expression "Calculated costs: " is displayed in the fields "Marginal costs" and "Production costs" so that the displayed values are not assumed to be fixed. The test values also influence the subtotals (material -, total wages). Here too, the costs are marked as "Determined costs" if they depend on variables (formula, table).
Documents
: Structure tree	Using the structure tree on the left side, subfolders or subnodes( ) can be generated. Associations (document references, parts, part roles, partner roles, etc.) can be moved within the structure via drag & drop and thus structured. In addition, it is possible to navigate via the structure tree to display the associations of the folder in the right-hand list. (At present only document references can be structured).
: List	On the right-hand side is the list of document references. The local document references are marked with the little house symbol ( ) and the global ones with the document reference icon ( ). In addition, global document references can also be inserted as a conditional table. Of the associated documents, the description of the document reference is displayed next to the type. This can be either the short title in the operating language or the description text. In addition, the type and the file name are displayed. link: Description of the buttons for maintaining the assignments to the document references
Description of structure node	For the folder (structure nodes) defined in the structure tree, a different description can be entered here and saved using the save button to the right of the field.
preliminary calculations
In this tab you can see the preliminary calculations already made for the part. You can also create a new preliminary calculation directly from this window using the "New preliminary calculation" button. If the "Transient" check mark is set, a transient preliminary calculation is created that is not saved in the database. Rows can be dropped directly into the list from the conditional table defined via specifications in order to trigger a precalculation.
: New preliminary costing	A new precalculation is created (see also field "Transient").
: Transient	If the button "New pre-calculation" is pressed a new pre-calculation is created either transient (will not be saved) or persistent (will be saved).

Production cost allocation or calculation

As a matter of principle, the production costs for a part are divided into two cost areas that are valued differently:
Wage costs and material costs.

The costs of a production part, taking into account all the necessary wage and material costs on the basis of the master parts lists and routings, are taken over by the preliminary parts calculation.

As a standard, the additional costs incurred in addition to wages and materials, e.g. for purchasing or stock management of the required parts, are included in the overheads. These are stored globally in the client.

However, the following approach is preferable in order to be able to calculate production costs precisely according to other costs incurred during production, such as machine running costs and programming costs, without having to include all costs invisibly in overheads:

In the part or at the work plan position, a material characteristic must be defined which contains the costs for e.g. the machine costs per hour according to the following format
costs = 120€/h (see below in the picture in the work sequence).

You must therefore create a material characteristic for each cost element.
The characteristic can also be stored directly on variant parts and can also calculate itself there from other boundary conditions (calculated or conditional characteristics).

To be able to take these costs into account, a formula in the resource of the work sequence is necessary (in the picture the standard costs of the working group):
Standard costs = formula = costs+(40€/1h)
Since the formulae do not know any compound units, instead of 40€/h --> write 40€/1h and put this in brackets.

The machine costs per hour specified via the material characteristic are now added to the standard machine costs per hour.

In order to check whether the costs are actually there without any error occurring, the formula can be extended by a query as follows

(if(has(costs))costs else (0?))+(40€/1h)

In this case, the system queries in advance whether the costs have been found and otherwise uses the value 0?, whose unit is based on the next component for further calculation.

In the preliminary parts calculation we then immediately see the result:

The marked line is our work sequence, which has received wage costs of 1.600€ for 600 minutes (10 hours) (120€ machine running costs + 40€ standard costs = 160€ per hour * 10 hours = 1600€)
