Use
You can manage objects of the Bill of material and Task list object types more specifically if you set the indicators for object sub-types accordingly.
Features
For each of these object types, the following table shows the object sub-types for which you can control processing individually via the change number.
Object Sub-Types in the SAP Standard System
Object type |
Object Sub-Types |
BOMs |
Materials Equipment BOM Document structure: Functional location BOM Standard BOM Customer order BOM Project BOM |
Task lists |
Routings Reference operation set Inspection plan Instructions Equipment task list Master recipe Rate routing Reference route rating Routing for functional location |
This means that you enter the
Object Type Indicators that control processing with reference to the change number separately for each individual object type you have selected. You can, for example, define that a change number can be used for material BOMs but not for document structures.Optional
If you maintain a simple change master record in the standard system (for example, with a valid-from date without a release key), the object sub-types are optional for BOMs and routings.
Required
The object sub-type is required for routings if you create a change master record with the following functions:
Because you cannot use these functions for every routing type, you cannot set an indicator for routings on the Object types screen. You cannot set this indicator until you have set the routing sub-type indicator.
Activities
You are in a change master record.
The Object type specification dialog box appears.
– Bill of mat. according to type in ECH (BOMTypSpec).
– Task list according to type in ECH (TLTypeSpec)

If you have already processed bills of material or task lists (for example, routings) with reference to this change number, there are limits to the changes you can make to the indicators for object sub-types. You can only reset the object sub-types indicator for an object type (for example, bill of material) to obtain a single entry again (for example, material BOM, document structure ® bill of material) if all object sub- types of this object type have the same indicators set for this object type.
