Data Services functional call to extract data from SAP

Hi everybody,

I want to extract data from SAP to Data Services through a functional call. First I created a RFC-enabled ABAP-function and a batch job that has the structure: Row_generation --> Query (incl. RFC) --> Query (unnest table) --> Table.

I already succeeded in extracting all the data avaialable through my custom function. So far, so good!

Now I want to restrict the output result by defining an input table (function is similar to this http://wiki.sdn.sap.com/wiki/display/EIM/Calling+RFCs-BAPIs).

Unfurtunately that did not work.

Can you help with that problem? Which steps do I have to follow?

Many Thanks,

Thomas
