FRM-40212 INVALID VALUE FOR FIELD DOC_NUMBER

Hi all ,

When User is trying to Enter the PO to forward , they are getting FRM-40212 INVALID VALUE FOR FIELD DOC_NUMBER Error .

I verified

a) if the Employee is attached against the User -Yes

b) If the User is defined as Buyer --Yes

c) if the Document Type security is setup as " Public "

Any other check points or any suggestions further ??

Thanks,

Deepthi
