Costing sheet not getting picked in CK11N

Hi,

I have assigned the costing sheet to the valuation variant which is then assigned to the costing variant. Now when I am running CK11N, the costing sheet is not getting picked.

What is surprising is that the costing sheet is getting picked properly in development and quality systems but not in production system. This is a fresh production system.

What is also surprising is that I am using the same costing sheet to derive a template (through OH group and OH key) and that template is getting picked properly. However, the overhead key and costing sheet does not get picked (as seen in the 'Valuation' tab of CK11N screen)

Any pointers what to check?
