Reproducing the Issue

1. Login into Customers Instance. Navigate to Admin Centre>Compensation>Variable Pay>Template Name>Manage Worksheets>Manage Worksheets. You can see that forms have been completed.

2. So, after this we would expect that we can Publish Completed Worksheets to Employee Central. So, navigate to Template in Question>Complete Compensation Cycle>Publish Data>Publish Selected Worksheets in Employee Central. Please choose Completed Worksheet(s) and click Submit.

3. Now, we can see the Job is in Process and the Job ID.

4. Navigate to Admin Centre>Monitor Jobs and we can see the Job Status is “Failed”.


  • According to the error logs for this issue, when publishing Varpay data to EC side, field types for the custom publish dates didn't match. The system is expecting "Date" type but found "String" type.
  • Reviewing the template XML we can find a configuration error:

< comp-hris-field-map>           
< /comp-hris-field-map>

  • EC field pay-day is always "Date" type while the defined Variable Pay field "EC_EFFECTIVE_DATE" (this is just an example) is, in this case, a "String" type field.


  1. Navigate to Admin Centre>Compensation>Compensation Home>Template in Question>Design Worksheet>Column Designer>Field containing the custom Effective Date and change the Column Type from String to Date.
  2. This change will require to relaunch forms so it will take place.
