Columns in the database views are created in upper case and the corresponding classes in Pega are mapped with lower case in the External Mapping tab. This is because the SQL Server Database is case sensitive and is unable to identify the exposed columns.


Perform the following local-change:
  1. Fetch the ruleset password to unlock the PegaProjectMgmt ruleset.
  2. Change the column names in the External Mapping tab for the below classes (Definition > External Mapping tab) with the column names from the respective database views. Save the classes.
