3710186 - Custom Manager is not accessible within Recruit to Hire for JobRelationsInfo

Custom Manager is not accessible within Recruit to Hire  data mapping for JobRelationsInfo.

1.Go to Recruit to Hire Data Mapping Admin Center Tool
2.Go to JobRelationsInfo
3.Click + sign and Custom Manager is not an option

For two picklist non unique external code were same. Hence, it is causing the issue.

The problem was due to non‑unique external codes. Both the Technical Manager and Custom Manager roles were using the same external code, which caused the system to render only one of them.

Each external code in the jobRelType picklist must be unique to avoid conflicts.
