Rank for the Same Effectivity Type
Use
A change object (for example, a BOM item) can be processed with reference to different change master records.
It may be that the following conditions prevail:
You must determine which rules the system uses to select the change master record.
Prerequisites
You have maintained an object with reference to different change master records of one effectivity type.
You have activated the rank indicator in Customizing for Engineering Change Management in the
Set up control data step.Features
Determining the Change Status without Rank
Rank is not activated in the standard system. The system determines the change status that was made with reference to the change master record that was created last.
Determining the Change Status with Rank
If you have activated the rank in Customizing, then you can determine the rank (in the change master record) that a change status adopts under the same effectivity type conditions.
The rank of a change master record determines whether the change is likely to be chosen or not. This likelihood grows as the rank number increases.
You change a BOM with reference to four change master records with the same effectivity type SERNR (serial number).
The following table shows the different ranks and release keys.
Change number |
Rank |
Release key |
A |
05 |
Released |
B |
30 |
Released |
D |
10 |
Released |
F |
35 |
not released |
Because the SERNR effectivity type has the highest rank and the changes are also released, the changes for change number B are taken into account.
