We have a problem with vendor rebate process. This is our process:
1. XK02 - Changing a Vendor Master Record (Activate "Subsequent Settlement" and "Sebseq. sett. index" in Purchasing view)
2. MEB1 - Creating a Rebate Arrangement
3. ME21N - Creating a Purchase Order
4. MIGO - Processing the Goods Receipt for the Purchase Order
5. MIRO - Processing the Incoming Invoice on the Basis of a Purchase Order
6. MEB4 - Creating a Final Settlement
In sixth step system alarms with next message: "G/L account xxxx requires a valid tax code", we think is about determination tax material relationated with dummy material for settlement rebate.
Any help??? I will revvard you!
