How To Fix APO_BAPI035 - Resource &1 does not exist in system group &2

APO_BAPI035 - Overview

• Message type: E = Error

• Message class: APO_BAPI - Message Class for APO BAPIs

• Message number: 035

• Message text: Resource &1 does not exist in system group &2

What causes this issue?

The system has tried to find the external key for the resource &V1&
(internal key) in the business system group &v2&. However, no mapping
entry could be found.
The master data is probably inconsistent.

How to fix this error?

Check whether an entry for &v1& for the resource exists in the mapping
table /SAPAPO/RESKEY. If there is one, check whether the accompanying
system group is the same as the system group &v2&.
If both system groups are not the same, it is possible that the data is
inconsistent. Check if the resource is used with other master data, and
if this belongs to the same system group. In certain circumstances, the
master data (product, resource, location, ...) from different system
groups is used. This is not allowed.
