Why am I getting unexpected results from weekly firm data viewer KPI?

Why am I getting unexpected results from weekly firm data viewer KPI?

The Issue here is the column_name with which the measure 'C4182' was created is not mapped to any of the levels in the db2_dbmodel.xml file. This is a pre-requisite for any measure to function properly. Map the column_name to the appropriate level in db2_dbmodel.xml to solve the issue.
