How To Fix V1690 - Master contract field '&3' is not valid for the lower level contract

SAP Error Message - Details

• Message type: E = Error

• Message class: V1 - Verkaufsbelegbearbeitung

• Message number: 690

• Message text: Master contract field '&3' is not valid for the lower level contract

What causes this issue?

According to the referencing procedure the &V3& field in table &V2&
should always be copied from the master contract &V1& to the lower
level contract, if it agreed with the lower level contract before the
master contract was changed.
Because this requirement wasn't met, the system did not copy the field.
