How To Fix APO_BAPI036 - Product &1 does not exist in system group &2

SAP Error Message - Details

• Message type: E = Error

• Message class: APO_BAPI - Message Class for APO BAPIs

• Message number: 036

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

What causes this issue?

The system has tried to find the external key for product &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 if there is an entry for &v1& for the product in the mapping
table /SAPAPO/MATMAP. If this does exist, 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 product is used with other master data, and
if so, if this all belongs to the same system group. In certain
circumstances, master data (product, resource, location, and so on)
from different system groups is used. This is not allowed.
