Column value does not populate



Column value does not populate and is set to null when importing it from a CSV file into a Data type. The value is present in Binary Large Object (BLOB) but does not populate in the column. However, the property displays as optimised.  

Error Messages

Not Applicable

Steps to Reproduce

  1. Open Data type
  2. Import data from CSV file

Root Cause

An issue in the custom application code or rules. Mapping of column and property is incorrectly recognized by Pega application since a space is present in the name of the column but not in the property.


Perform the following local-change:
  1. Add the column and property in the External Mapping of the class
  2. Import CSV file

Alternatively, resave the values in the Data Type through an activity using Obj-Browse and Obj-Save methods.
