Control message in F-47

Dear Experts,

I need to know whether there is a way to control the message F5 371 - Purchasing document belongs to another supplier . SAP does not allow to change this message in message control. (SPRO>Investment Management>Appropriation Requests>Master Data>Control Data>Maintain Message Control)

This is only a warning message in F-47. I need to make this to an error. Please give your ideas.

Regards,

Jeewana
