Diagnosis
Process interfaces are designed to replace a process within the SAPstandard program. This means that within a user group (SAP, partner orcustomer) only one Add-on should be active. The process interface &V1&is not designed for filtering with regard to country or industry.
An additional entry is therefore not possible.

System Response
Error message

Procedure
Check whether two entries for &V1& are necessary.
If so, you can rectify this problem by incorporating the functionmodules that are assigned to interface &V1& in one function module.
