Bill of materials information is recorded in the following fields and BOM revision lines of the window:
- General Info
- Main Product
- Revision
- Route Information
- Planning
The upper pane of the Bill of Materials window contains basic information that is not affected from engineering changes. The fields on the General Info and Product sections and their relative functions are:
Code: The record code of the bill of materials. This field can contain up to 24 alphanumeric characters, and can be sorted and searched. Alphanumeric characters can be used to define the code. This field is mandatory. Production orders are issued using the bill of materials code specified on this field.
Description: The name or the description of the bill of materials.
Aux. Code: The aux. code of the bill of materials. The code allows the user to classify the bills of materials by company specific criteria. The string is 10 characters long. Alphanumeric characters can be used to define the code.
Authorization Code: The auth. code of the bill of materials. Used to define detailed authorizations. The string is 10 characters long. Alphanumeric characters can be used to define the code.
Status: Indicates the usage status of the bill of materials. The status field has two options: Active and Passive. Bills of materials with passive status cannot be used in production orders.
Product Information
Product Code / Product Description: The code of the product to be produced using this bill of materials. The bill of materials can be defined for a
- Material
- Material Class
When Material is selected, the code of the product (finished product) to be produced using the bill of materials is selected from among the materials defined in the system. Only the Finished Product, Semi Finished Productand Material Class type records can be selected from the materials list accessed through this field. Otherwise, the user is warned with "Material type does not match" message.
When Material Class is selected, the bill of materials is defined not only for materials, but for the selected material class as well. Bills of materials defined for product groups (classes) can be applied either to all the materials within the class or only a part of them. In this case, the materials to be produced and their quantities are recorded using "Apply Distribution Template" or Material Table options depending on the material class type selected in the bill of materials line.
Product Line Code: This field is used to specify the product line to which the product is related. The product lines are listed, and the appropriate definition is selected.
The lower pane of the Bill of Materials window contains the information affected by engineering changes called as Revision, and the lines where the related input/output materials are defined. The fields containing the Revision and related Input/Output Lines and their functions are:
Revision / Route Information
Revision Code / Description: The revision code of the bill of materials. When an engineering change is performed, bill of materials information is tracked and filed by revision numbers.
In the LOGO application, each change to the materials performed after engineering changes is kept as a separate revision record and tracked according to the bill of materials record.
Route Code / Description: The route code of the bill of materials revision. The route definition is used to specify the operations that the materials will pass through in the production transactions performed using the bill of materials. The Route Code is selected from among defined production routes.
Overhead Formula (Local / Reporting Currency): The field on which the overhead default of the bill of materials is entered in local currency and reporting currency, or the formula is generated.
Quantity Related Time (Min.) / Non Related Time (Min.): If the Planningsection of the LOGO application is used, the time information to be used in the Master Production Schedule (MPS) and Material Requirements Planning (MRP) transactions is entered on this field.
Overlapping Type: The overlap quantity or rate entered on this field is used when the production start date is calculated in planning transactions. The field contains three options:
- None
- Quantity
- Rate
If Quantity is selected, the overlap quantity is processed when the production start date for the semi-finished products of input type is calculated. When the bill of materials is used in production, the value indicating the portion of the quantity specified in the previous production order to be produced for the next production order to be started is entered into the overlapping quantity field. If rate is selected, the same transactions are performed by processing the rate specified on the Rate field.
Examples
BOM.001
Fixed Lead Time: 10 minutes
Variable Lead Time: 10 minutes
Overlap : None
Product MM.001 : 1 unit
Input YM.001: 1 unit (Procurement Type: Production)
BOM.002
Fixed Lead Time: 10 minutes
Variable Lead Time: 10 minutes
Overlap : Quantity 40
Product YM.001 : 1 unit
Input YM.002: 1 unit (Procurement Type: Production)
BOM.003
Fixed Lead Time: 10 minutes
Variable Lead Time: 10 minutes
Overlap : Rate (20%)
Product YM.002 : 1 unit
Input HM.001: 1 unit
According to the data above, 100 units of YM.001, 100 units of YM.002 and 100 units of HM.001 are required to produce 100 units of MM.001.
The time difference between YM.001 production and YM.002 production is calculated with the
(100 (production quantity of YM.002) * 20% (overlap rate of YM.002)) * 10min (fixed lead time of YM.002)+10min (variable lead time of YM.002) formula, while
The time difference between YM.001 and MM.001 production start date is calculated with 40 (overlap quantity of YM.001) * 10min (fixed lead time of YM.002) +10min (variable lead time of YM.002) formula.
