RN20BizDocType Error


My trading partner is sending a PIP3A8 Purchase Order Change Request to my webMethods system. This will then trigger the PIP3A8 Seller conversation script in my system. However I am seeing RN20BizDocType being triggered instead of the standard Pip3A8 document type. Has anyone encounter such a problem also ?

Note: I am using webMethods 4.6


Check the identification queries that you have defined for 3A8 in TN against the document received from the partner. Seems to be an identification problem.
