Hiring Manager-search issue in erecruitment

Hi experts,

We are working on Erecruitment module ehp6

For employee manager relationship we are using B012(chief position) not B002

We are not able to use search option for the hiring manager field in the Create Requisition screen

The search option does not retrieve any results even if managers are maintained as the chief of the org unit..

Kindly help,

Regards
