ME21N Limit PO type M_BEST_BSA using PR type M_BANF_BSA

Hi experts

Question for PO creation ME21N.

Let's say I have various PR/PO types - example to use to restrict let's say PR type ZPR and PO type ZPO.

I want to restrict PO creator from picking up ZPR type.  Do you know if this will work i.e. remove M_BANF_BSA from PO creator role? 

Thank you!
