You can define a selection ID in this menu option that can be used for determining alternatives on the basis of priorities.
You are using the standard application INST for plant maintenance. You can now allocate a selection ID (03 in the standard system) to the standard application INST, by means of which you can define the determination of BOM usages by priorities. BOM usage 4 is assigned to selection ID 03 in the standard system with the highest and only priority. If you have several BOM usages for plant maintenance, you define the order of the usages here. This assumes that you have already defined several BOM usages for plant maintenance.
In the standard SAP delivery, the BOM usage 4 is assigned to the selection ID 03 with first and sole priority.
If you have changed the selection term INST for the selection of an alternative, you must use the appropriate selection term here for the alternative selection.
SAP recommends that you accept the settings defined in the standard system. In this case, no action is required on your part.
Configure the selection IDs for your maintenance BOMs.
