Call a Z RFC function to add a PDF File as business object to a purchase order --> RFC_START_PROGRAM not found

[BerniUhr]

Hi,
I wrote a Z RFC Function:

FUNCTION z_rfc_doc_to_archiv.

ENDFUNCTION.

Now if I try to invoke this RFC an Exception is thrown with this failure message:
RFC_NOT_FOUND (rc=17): key=RFC_NOT_FOUND, message=Function RFC_START_PROGRAM not found [MSG: class=, type=, number=, v1-4:=;;;]

The function works, if I test it on the quality system directly. But invoked from external system the failure comes.

result = self.conn.call('Z_RFC_DOC_TO_ARCHIV',DATEIPFAD=pfad, OBJEKT_ID=objekt_id, SAP_OBJEKT=sap_objekt, DOKUMENTART=dokumentart, DATEIENDUNG=dateiendung)

Is ARCHIV_CREATE_FILE the wrong function for this. It seems to search for a callback. And is there an alternative function that doesn't need a callback function in my Python Code (I would prefer)?
Or is there a way to implement the callback function in Python?

Best regards
Bernhard

I am not familiar with ARCHIV_CREATE_FILE function module and what it exactly does and would suggest to ask this kind questions in SAP community.

is there an alternative function that doesn't need a callback function in my Python Code

This is something ABAP developer or SAP Community can help find out

is there a way to implement the callback function in Python?

Not really. PyRFC supports also server scenario, so that ABAP can call Python function over RFC channel, just like it calls ABAP function module. Replace ABAP callback function with Python would be easy, in case the function does something like adding two numbers. That is unfortunately not the case, ABAP functions call other ABAP functions etc. and moving one isolated ABAP function to Python is in general not possible.

I would try to find answer in SAP community if another function is available, without callback, doing the same.
