Maintaining the Create Material BOM Initial Screen The Create Material BOM: initial screen screen appears. On this screen, you maintain data that identifies the bill of material, as well effectivity data.
-
If you do not know the material number, you can look for the material using the entry help (F4).-
If the material for which you want to create a BOM has a material type that cannot be used in combination with the BOM usage you have entered, you see an error message.See
– If you want the BOM to be effective in a specific plant, enter the plant. You can allocate the BOM to additional plants later on under certain circumstances (Create allocation of BOM to plant).
– If you want to create a group BOM, do not enter a plant.
If a parameter is defined in your user master record as a default value for the Usage field, the system enters this default.
When you select a BOM usage, you define the maximum range of item statuses that can be assigned to all items in the BOM. For each usage, you can only maintain certain item status indicators.
See Defining the Item Status with the BOM Usage.
You cannot change the usage at a later date. However, you can create other BOMs for the material (in the selected plant) with different usages.
When you create a simple BOM, you do not need to enter an alternative.
– If you do not make an entry when you first create a BOM, the system automatically creates alternative 01.
– If you already know when you first create a BOM that you want to extend the BOM to make a multiple BOM, and that this alternative is not alternative 01, enter an alphanumeric value.
Maintain the data on the effectivity period:
– If you want to create the BOM without a change number , do not make an entry in the Change number field. Enter the date on which the BOM is to become valid in the system in the Valid from field.
– Enter a Change number if you want the BOM to have a history requirement as soon as it is created. If you enter a change number, you must enter a valid change number each time you want to change or extend the BOM.
Usually, you only process a BOM with a change number once the BOM has been released for production.
When you select a change number, you need to consider the following points:
– Which object types (for example, BOMs or task lists) can be processed with this change number
– Which effectivity period will the change number give the BOM (valid-from date)
– The reason for the change
The system copies the valid-from date from the change master record into the Valid from field.
– If you want to create a BOM for the material at a certain revision level, enter the revision level.
If you display the possible entries, you see a list of all revision levels for the material. The change numbers with their valid-from dates are assigned to these revision levels.
– Copy the revision level you require by double clicking.
The system enters the valid-from date from the change master record in the Valid from field.
.The system makes a series of checks. For example, the system checks whether the material master record exists in the selected plant and whether the material type can be used in combination with the BOM usage.
When all data is correct, you goto the item overview of the BOM.
