GW Function Import: pass parameter table (e.g. multiple parameters of same type)

[Former Member]

Hello GW experts,

we have defined a Function Import "CreatePOWithReference" with a parameter "Reference" which contains a string with information about a reference document which shall be used to create a new Purchase Order (PO):

Now I would like to pass not only a single reference but multiple reference all of the same type "Reference".

I tried calling the function import with two references like this:

/sap/opu/odata/sap/ZMP_ODATA_PO_SRV/CreatePOWithReference?Reference='123'&Reference='456'

But in method "/IWBEP/IF_MGW_APPL_SRV_RUNTIME~EXECUTE_ACTION" my parameter table "IT_PARAMETER" only contains 1 single record:

How can I achieve that the table "IT_PARAMETER" contains two records (Reference='123' and Reference='456')?

Thanks and best regards,

Oliver

PS: As there can be any number of references, it is not an option to create several parameters "Reference1", "Reference2", "Reference3" and so on... .

Yes,

Exactly what Sreehari and Ashwin said it's correct you can not pass as a multiple value at one time..so that you can perform batch or create deep entity method you have to implement.

Thanks,

Hello Thomas,

In my opinion, i do not think you can pass same property multiple times as you are trying now. I really doubt if GW supports this and IT_PARAMETER has only one Reference ( which is sent 1st i.e., 123 ) as you have already shared values read at runtime.. As per my understanding it is the correct behavior of GW where only one reference number - 123 is present in IT_PARAMETER table.

Other standard way of accomplishing your business case would be implementing CREATE operation and operate it on BATCH.

Hi Oliver,

In my knowledge, function import can not accept multi line items . You can implement a deep entityset and map the internal table fields.
