A new token is required to populate the internal job requisition title in the Offer Letter regardless of the candidate type.
SAP SuccessFactors Recruiting Management
As of now, the [[JOBREQ_TITLE]] token currently available in Manage Offer Letter Templates populates the job requisition title depending on the candidate type.
Please refer to KBA 2162125 - Job Title Token [[JOB_REQ_TITLE]] - Recruiting Management, which describes the same behaviour.
An enhancement request for this has already been submitted. Please review Request ID 241284 and feel free to vote for it.
A possible workaround could be to configure a custom field in the job requisition with a business rule that fills out the information based on the internal job title and then this field could be used in the offer letter. Please reach out to your Implementation Partner or Professional Services.
