BAPI_MATPHYSINV_GETITEMS

Hey,

I'm trying to create an Odata Service which displays the Items from via RFC 'BAPI_MATPHYSINV_COUNT' .

But I have a Problem, i just want(can) to use 1 of the export tables. In this case just the ITEMS. So if I try to create Query for it, it shows me 'Mandatory data source parameter HEADERS is not mapped'.

But as soon as I Map a parameter from HEADERS it says 'In Query operation, only one output table can be used', which both makes sense.

I there any workaround for that? what am I doing wrong?

Thanks in advance
