Hi Experts,

                i have an Peculiar situation,Having enabled change pointers, and executed RBDMIDOC for type COSMAS, every entry I created or changed, it got updated in table. When I generate the resulting IDoc all have MSGFN or status = 005 and my non-SAP receiving system cannot distinguish an add from a change or a delete. Am I missing additional config settings ?Help Required.please check screen shots below, relevant to problem.
