I am doing FB70 transactions for raising the debit memo to the customer and am facing the following problem and the system is not allowing me to save the document.
Item category 03000 not allowed in accounting transaction 0200/0001
Message no. GLT2001
The online document splitting is active in your system. Here, each document is assigned to a accounting transaction variant and each document row to an item category.
You determine for each business transaction variant which item categories can or must be posted here.
The following error occurred for the document you entered:
Item category 03000 in accounting transaction 0200, variant 0001 is not allowed.
The document cannot be posted.
Check the document entered, the derivation of the business transaction variant, the derivation of the item category, and the assignment of the item categories to the business transaction variant.
