3. Common Real-Time MM Errors & Solutions 🚨
Master these essential solutions for handling procurement and inventory issues.
Error 1: "Posting Only Possible in Periods..."
Scenario:
User is trying to post a Goods Receipt (MIGO) but the current month is closed for Material Management transactions.
Solution (T-Code: MMPV / OMSY):
Use T-Code MMPV to open the new posting period (month). This must be done sequentially, month by month. Alternatively, check the company code settings in OMSY.
Error 2: "Account Determination for Entry XXXX not possible"
Scenario:
During Goods Movement (GR/GI), the system cannot automatically find the G/L account (Integration MM-FI) required for the transaction.
Solution (T-Code: OBYC):
Check Automatic Account Determination using OBYC. Ensure that the correct Valuation Grouping Code is linked to the Transaction Key (e.g., GBB, WRX) and the appropriate G/L account is assigned.
Error 3: "Field Account Assignment Category is Mandatory"
Scenario:
While creating a Purchase Order (PO), the Account Assignment Category field is missing or not accepted for that specific Material Type/Item Category.
Solution (T-Code: OME9):
Customize the screen layout for the specific Account Assignment Category (e.g., 'K' for Cost Center) in OME9 to ensure the necessary fields are visible and required.
