SAP Business ByDesign

Reproducing the Issue

  1. Go to Master Data Replication work center
  2. Select Replication Runs view
  3. Select the respective application log 

Then you can find error.


The issue might be due to incorrect data setup for some of the employees in the system. If you try to Upload Data from Employee Central for these employees, you can see issues such as Replication of Supervisor/Managers for these employees is missing.

When you open the Replication Request file, you could also notice below issues under Organizational Assignment Tab:

  • Duplicate Entried for Reporting Line Units
  • Overlap in the Validity Periods for Org Units

This kind of data setup (Overlap in Employment) is not supported scenario for Replication to ByDesign.

Due to such incorrect data setup, system is encouraging scenarios which are not expected, and Replication Runs are failing.


The data would need to be corrected from customer side in the connected EC system. Please replicate Supervisor/Manager files and then replicate these employees again.
