Planning area activation error

Hi,

While planning area activation, I get the following error. I'm not able to tell if it is because of a key figure or attribute or master data type. There is no entity named CUSTNUM in the planning area, so I'm not sure what the error is referring to?

E - Exception raised from  InternalError: dberror(PreparedStatement.execute): 2048 - column store error: fail to create scenario:  [34011] Inconsistent calculation model;CalculationNode (3_87) -> operation (CustomLOp):Input table '3_86' has no column 'CUSTNUM' in the model at ptime/query/plan_executor/trex_wrapper/trex_wrapper_body/trex_metadata.cc:2082

Detailed log attached.

Please guide.
