2518461 - Unable to Create Leave of Absence Time Types after Picklist Migration to MDF

After legacy to MDF picklist migration, validation error below is shown when creating Leave of Absence time types:

"One of the required events for Leave of Absence is missing in the event picklist. Please make sure the absence start and absence end events are available and have the pre-defined external codes."

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

1. Go to Admin Center > Manage Time Off Structures.

2. Create new leave of absence time type and save the changes. An error message is received.

Non-unique external codes for the LOA related event picklist values are not defined in the MDF picklist causing an issue since all picklist fields and pages within the application would no longer refer to the external codes post migration. See KBA 2504047 and 2328179.

NOTE: This can only occur if sync was disabled before the picklist migration process

Maintain non-unique external codes for Leave of Absence related picklist values in Admin Center > Picklist Center or via MDF Picklist Import.
