Diagnosis
The address (name: &V3&) that was still used as selected partneraddress in contract account &V1& with partner &V2& has been deleted inthe business partner.

Procedure
Use the pushbutton account to go to maintenance of contractaccount &V1&. From here, select a different business partner &V2&address and apply the changes. We recommend that you select thestandard address for the partner in the contract account instead of aspecific address. The advantage of this is that whenever you make achange to the business partner address, the standard address is alsoautomatically used in the contract account.
These changes are then saved when you save the current businesspartner.
