SAP Error Message - Details

• Message type: E = Error

• Message class: 1G - BKK: Konditionen

• Message number: 250

• Message text: The combination of the differentiation types &1 and &2 is not permitted

What causes this issue?

For a condition you have entered the differentiation types &v1& and
&v2&. This combination is not permitted. You can differentiate a
condition either according to transaction type or according to a
transaction type category.
Before using a condition, all the differentiations used must be
fulfilled. If you differentiate according to transaction type and a
transaction type category, this condition is only used if the specified
transaction type is contained in the category. In this case it is
sufficient if you differentiate the condition with the transaction type
category.
If you specify two transaction type categories as differentiation
types, the condition is only used for transaction types contained in
both categories. The different transaction type categories were created
to enable you to group transaction types according to different
criteria.
