Data Type columns are not populated



When importing a data type using CSV, values do not display for the Key Column.
In the database, column does not display values. However, on opening the instance and viewing the XML property, the values are present. That is, the BLOB has the values, but the exposed column does not display the values.

Error Messages

Not Applicable

Steps to Reproduce

  1. Create a Data Type.
  2. Add Properties.
  3. Configure the data source.
  4. Export the CSV and import after adding entries.

Root Cause

An issue in the custom application code or rules.

Two properties exist with the same name. However, the name for one property is in Camel case while the other is in lower case.

For example:

Property 1: TestProp
Property 2: testprop

TestProp is present in @baseclass and testprop is present in the data class which is optimized. Pega does not recommend this type of duplicate properties. Thus, the properties are mapped incorrectly to the database columns. That is, TestProp is mapped to the database column instead of testprop.


Perform either of the following local-changes:
  • Add the external mapping in the data type class.
  • Delete the property from @baseclass. This must be deleted from all the environments as the deletes are not exported.
