In the reports tab , I see send time stamp as null for the incoming message for a particular partner , but it is getting populated for all other partners . Do you know what can be the possible cause and how does send timestamp gets populated ?
I am have the same problem as the OP. The send time stamp field is NULL in B2B console for a specific partner's inbound docs, but the field is populated for every other partner. The exchange protocol is AS2 and the document protocol is EDI_X12.
