FM idoc_input_shipmnt

Question

Hi,
I'm using FM idoc_input_shipmnt in order to update a transport document.
I want to update the loading start date and hour(fields VTTK-DALBG and VTTK-UALBG in the transport document). I'm calling This FM from idoc SHPMNT04 (SHPMNT).
I'm always having the following error.
"Processing terminated because not required or possible".
I do not know if It is a problem of mapping or It's due to something else.
Do you know for sur If FM idoc_input_shipmnt allows to update the transport document whith the data I need. if yes do some one have the correct mapping.
If not do you know what is the FM allowing to do that
Thanks in advance

Answer 1

I don't use the external id. I'm using only the shipment number. All the fields "external id" are blank in my transport document.
I have been trying to use different mapping values in my idoc.
When I put the value
E1EDT18-QUAL = PID and
E1EDT18-PARAM=TKNUM
I have the following error : "Externally specified shipment 0000519936 is invalid"
If I try with
E1EDT18-QUAL = PID and
E1EDT18-PARAM=''(Blank)
I have the following error (Status cannot be set because status "planned" has not been set). But my transport is in the correct status and It has been planned it's not the problem and I tried with many transports.
And when I try with E1EDT18-QUAL = CHA (And whatever the value of E1EDT18-PARAM is), I'm having the usual message error (Processing terminated because not required or possible).
Do you have any idea about what the problem is?
Thanks in advance
