Configure Standard PO instead of X-Company STO

Hello,

Currently my company has configured the system in a way that when they want to Procure Stock from another location that is in a different Purchasing Organization/Company Code, automatically the system changes the PO Document Type to ZUBX (X-Company STO), but they want to change some of them to be a Standard PO (NB) so it falls under Release Approval through Regulatory Compliance Office.

Any help will be greatly appreciated.

Thanks.
