Hi
I have followed this guide: http://scn.sap.com/docs/DOC-16334 and created the Gateway service with succes :-)
Now I want to create following:
A list of Purchase Orders on behalf of vendor number. Pretty simple, but...I have problems.
In our ERP system, I have created the PO (RFC enabled).
Import parameters:
LIFNR type ELIFN
Exporting parameters:
E_EKKO type EKKO_TTY.
In SE80 I have created my GW datamodel, but I have some issues and questions.
I just want my list of PO's for my choosen vendor.
Is it necessary to create a query? I am asking this question, because I see in the "how to guides", that the query is created, but on behalf of a FM like GET_ALL_LIST - and I don't have a FM like that, but should I create a FM to get all PO's?
Further I try to create the operation type READ, but I am facing problems in the mapping.
I choose LIFNR (below E_EKKO[]) and then pressing the "Change Mapping Route" .
The result is following error: "Property can only be moved to Data Object with same cardinality".
My search didn't help:
