In BUP3 T.Code, using ‘’Open BP’’ option not able to display Customer after displaying Vendor.

Hi,

In the BUP3transactioncode, assume I opened the Purchasing view of the vendor, thenusing the ‘’Open BP’’ option if I opened another customer number(This BP does not have Purchasing Role.), Now the BUP3transactioncode is expecting to have a Purchasingrole for the customer also, and giving an error ‘’Businesspartner xxx does not exist in the role Vendor(purchasing)’’.

Is there a way to solve this issue?

Thanks in advance.
