Diagnosis
The variant that was active when the termination occurred tried todelete billing line items or set them to inactive. However, the itemsto delete include items that have been defined as belonging to a pricesummary.
Price summaries can only be deleted or set to inactive completely. Inthis case, at least one of the billing line items that is part of theprice summary could not be deleted. It is likely that a contrary outputoperand (operand type AMOUNT) has been used in one of the correspondingschema steps.
Partial deletion is not possible, as it could result in roundingdifferences that could no longer be corrected. The correspondingconfiguration in the schema is highly irregular. Still, if youabsolutely require this configuration, please report the termination toSAP.

Procedure
Check the corresponding schema. All the steps involving price summarymust have the same output operand for operand type AMOUNT in order toenable deletion (or setting to inactive) in a subsequent step.
