2218846 - Instance Synchronization Tool : Syncing Legacy Picklists shows External Code not Unique error

SAP SuccessFactors HCM Suite

Reproducing the Issue

  1. Logon into SAP SuccessFactors environment
  2. Go to Admin Center > Instance Synchronization Wizard
  3. Select Configuration Copy (Instance Synchronization)
  4. Try to sync Legacy Picklists and get the following error message:"External Code not Unique"


From the 1505 release onwards, syncing picklists requires a unique External Code to be assigned for each existing picklist option, or it cannot be successfully synched.


The external code field on the picklist file should be populated and unique on both source and target, and it should be identical before we do the sync. The sync will consider the PicklistID + External code criteria to match the records across source and target.
