[Problem description]
When a user settles import purchase tariffs (transaction code MIRO), he hopes to specify the WBS inventory material directly on the "Material" tab. However, he finds that no matter how he adjusts the WBS element field, the system does not display it on the "Material" tab. What is the reason? How should the business handle this?
[Problem Analysis]
1. During purchase settlement, the system records the GRIR credit and GRIR debit in the underlying data table RBMA, but: there is no WBS element field POPNR in the data table RBMA.
2. Therefore, during MIRO settlement, it is not possible to settle to: special inventory, WBS inventory materials in one step.
[Solution]
If you must do this, you can consider using the two-step method:
1. MIRO settlement to a common inventory material.
2 MR22 transfers the amount of common stock materials to material special stock (WBS). Note that MR22 needs to be configured with a separate revaluation reason.
3. After adjustment, check out CKM3N.
