Group OAS_PRIM cannot be used

Dear Friends,

Using T.code Ko12(change Overall planning),I entered Order no and selected the current fiscal year and clicked on primary costs. I get the error as mentioned below.

Group OAS_PRIM cannot be used

Message no. K8001

Diagnosis

Group OAS_PRIM has not been created in controlling area OAS_PRIM for the characteristic used, neither does it exist as a node within the group.

System Response

The SAP System rejects the row/column structure for group OAS_PRIM.

Procedure

1. Create group OAS_PRIM with the group maintenance transaction.

2. Or, correct the name of the group in planning layout or in the initial screen for planning.

I have already created OAS_PRIM in T.code KOH2(Change Order Group).Yet, I am getting the error.

Please advise how to solve the error.I am working on 4.7V.

Regards

Sridhar
