Hide job field on PPOSE

Hello Experts,

Would you kindly let me know how I can hide the job and the code description or any related information from showing up on PPOSE transaction. I'm not sure if this is possible, if not, then at least I would like to hide JOB (JOB_P1000-STEXT) from the Basic Data tab available for the positions.

I'm thinking that this can be done on the hierarchy framework, but not sure what steps to take.

Anyway, all your responses are very appreciated.

Thank you.
