we have an issue with our client.
We have 2 types of AuC: the first one (let's say AUC_1) has only 2 depreciation areas (10 / 90) and the second one (AUC_2) has 3 (10 / 90 / 91).
A user created an AuC using AUC_1, instead of AUC_2.
We tried to transfer the costs using ABUMN but the area 91 does not get populated (we can see a movement but with 0 value).
We checked the customizing and area 91 should be derived from 90.
Do you have any idea how to populate the 91 depreciation area?
