Inbound SHPMNT05 error - Service Agent not copied from deliveries

Hi All,

Im using:

idoc SHPMNT05

message type SHPMNT

FM IDOC_INPUT_SHPMNT

I'm unable to change an existing shipment (tx: VT02n) with the SHPMNT05 idoc.

I've tried both message types SHPMNT and SHPADV..both fail.

The error I'm getting most is "Service agent not copied from deliveries - none exist"

Message no. VW153

I have also tried the following:

Create output SHPMNT05 idoc from a shipment.

Delete that shipment.

Input that idoc again with WE19 (making some changes ofcourse)...but still getting the same error.

OSS notes regarding this FM are implemented aswell.

Any ideas ??

cheers

Eric
