I have a TPE enabled orchestration followed by a non tpe enabled bam updates through components out side biztalk. The incomming message does nto have a unique identifier. so If let TPE assign the default guid to the activityid, is there a way to access it from the orchestration?
i need to pass this id to the non Biztalk components to update the BAm.
Are you sure the messages don’t have anything to uniquely identify themselves? This doesn’t have to be a single field. It could be a combination of fields. If you really need the TPE to assign an arbitrary activity ID that you can accss from an orchestration, then a good way to do it is to have the TPE use the BTS.MessageID or BTS.InterchangeID. These context properties will be unique, and you can access them from within an orchestration. Note: The InterchangeID is only unique for each interchange, so if you are slitting files on the incoming pipeline, you probably want to use something else.
