Answer 1

Can you please confirm if the following settings exist in your system in various IMG nodes.
1. Bank G/L account is assigned to item category 04000 (IMG node: Classify G/L Accounts for Document Splitting).
2. Document type KZ is assigned to business transaction 1000 and transaction variant 0001 (IMG node: Classify Document Types for Document Splitting).
3. In IMG Node "Define Document Splitting Rule", under the method that is assigned to your company code, transaction 1000 and variant 0001, you see 04000 as one of the item categories to be edited.
4. If the answer for (3) above is yes, if you double-click on 04000 item category line, the processing category is set to 1 (Splitting based on base item categories).
5. Now when you double-click on 'Base item categories', you see 03000 - Vendor as one of the base item categories in the list there.
Please respond with Y / N to the above questions and we can go from there.
