Block an article from vendor in Return PO entry

Hi,

User wanted to block an article from getting created in a Return PO.

It is vendor-specific and article specific.

However, it should allow Standard PO to be raised.

I had checked the "Article Status" in article master but it seems to block both Standard PO and return PO.

Is the any other place where by I can blocked it ONLY for Return PO?

Thanks
