Error occurs on summarizing and drilling down the report



When using the out-of-the-box Summarize feature on a report mapped to a data class, summarizing works correctly. However, error occurs on drilling down the report on clicking any row. The columns are mapped correctly to the external table.

Error Messages

InvalidReferenceException .pyLabel Unexposed properties cannot be selected for classes mapped to external tables.

Steps to Reproduce

  1. Summarize a report.
  2. Drill down the report.

Root Cause

An issue in the custom application code or rules.

The error occurred because the system performed a drilldown to the pyDefaultReport version in the @baseclass. This version has a property column which used the .pyLabel property and which is not exposed in the class of the report.


Perform the following local-change: 
  1. Save As the out-of-the-box pyDefaultReport which is available in the @baseclass to the user's class and ruleset.
  2. Remove the unexposed properties (pyLabel, Entered on).
  3. Add the required columns.
