SAP Note 16750 - Condition type DIFF not determined in bill. doc.

Symptom:

Condition type DIFF is not determined in the billing document, even though an appropriate entry has been maintained in table T001R.

Cause and prerequisites

The problem is caused by a Customizing error.
The problem is that condition type DIFF is not set to condition category = "L" in Customizing. As a result, this condition is not updated in the billing document.

Solution
Set condition category = "L" for condition type DIFF in Customizing. As a result, condition type DIFF will appear twice in all billing documents for existing orders. This does not pose any problem, however, and can be ignored.

Additional key words
