• Message type: E = Error

• Message class: AH - IS-U billing (master data)

What causes this issue?

You are updating an amount in schema step &v1& with variant &v2& to
schema step &v3& with variant &v4&. In the rate, you have specified for
variant &v2& that the values in the target step are to be overwritten
(not added to). This is not permitted since variant &v4& is a deletion
variant.
Deletion variants can only compare the amount and delete the
corresponding billing line items correctly if an "adding" update is
performed.
