Agent Determination - Rule - Function Module

[Lowe, Henry]

I have implemented a rule based agent assignment using a function
module. For some reason the statement 

swc_get_element ac_container etc is not working. I initially tested the
workflow as a whole and then did the 'simulate rule resolution' in PFAC
and have narrowed it down to this statement. 

I have put the include <CNTN01> in my global data for the function
group. 

Here is the code in the function module: 

FUNCTION z_get_po_creator. 
*"----------------------------------------------------------------------

*"*"Local interface: 
*"  TABLES 
*"      ACTOR_TAB STRUCTURE  SWHACTOR 
*"      AC_CONTAINER STRUCTURE  SWCONT 
*"  EXCEPTIONS 
*"      NOBODY_FOUND 
*"----------------------------------------------------------------------


DATA: l_user LIKE wfsyst-initiator, 
      l_ebeln TYPE ebeln. 

CLEAR:   actor_tab. 
REFRESH: actor_tab. 

break-point.           "For Testing Purposes Only 

* Get the PO Number from ac_container 
  swc_get_element ac_container 'PONUMBER' l_ebeln. 

  IF sy-subrc EQ 0. 

  SELECT SINGLE ernam FROM ekko INTO l_user WHERE ebeln EQ l_ebeln. 

     actor_tab-otype =  'US'. 
     actor_tab-objid =  l_user. 
     APPEND actor_tab. 

  ELSE. 
     RAISE nobody_found. 
  ENDIF. 

ENDFUNCTION.

 

And finally, below are the contents of the ac_container itab from debug
mode. 

ELEMENT TAB_INDEX ELEMLENGTH TYPE VALUE 
PONUMBER |000000 |000 | |4800000013 

A single step through the statement 
swc_get_element ac_container 'PONUMBER' l_ebeln. 
returns an sy-subrc of 4 and l_ebeln is not filled. ' 

PONUMBER' is the name of the container element on the rule and it has
the same type as l_ebeln. 

I am stuck now, can anybody help?

Thanks,

Henry.
