Help needed in Rules in workflow

Question

Hi all,
         I am beginner in workflow. I was trying to apply custom rules in my workflow design. I did the following steps :
1.  have created a custom rule through the transaction PFAC_INS.
2. There I have used a function module for the determination of agent. The custom function module will give me the superior name for an employee.I have used ztables to store the name of the employee and their superiors.
3. The Rule has been successfully created and has been tested. It is working as required. I have tested it in PFAC itself by using Simulation button.
The problem I am facing is
When I am trying to use this Rule in the workflow at the User decision Step it is not working. I have given the Rule number in the Agent section of  the User decision step.
According to my Workflow design the email should go to the Superior of the employee but instead it is coming to my Inbox.
Please suggent me what to do.
Thanks in advance.
Points will be rewarded for good suggestions.
Thanks & Regards.

Hi Raj,
          I have created a custom rule and its working fine. Please check the following steps:
The rule I have created gives the superior name of an user/agent.
Steps:
1. I have created a ztable( ztest_users)which will contain the name of users and their superiors.
2. Create a custom function module(ztest_find_superior) which will return back the table containing all the superior information for a particular user/agent.
Note: This custom function module created should have the same interface as that of the SAP standard function module RH_GET_ACTORS.
The following table’s parameters have to exist in the custom function module.
                   ACTOR_TAB STRUCTURE SWHACTOR
                   AC_CONTAINER STRUCTURE SWCONT
Example:
FUNCTION ZTEST_FIND_SUPERIOR.
""Local Interface:
*"  TABLES
*"      ACTOR_TAB STRUCTURE  SWHACTOR
*"      AC_CONTAINER STRUCTURE  SWCONT
*"  EXCEPTIONS
*"      NOBODY_FOUND
  INCLUDE <cntn01>.
  TYPES : BEGIN OF ty_users.
          INCLUDE STRUCTURE ztest_users.
  TYPES : END OF ty_users.
  DATA: org_agent LIKE wfsyst-agent,
              lt_holders TYPE STANDARD TABLE OF swhactor,
              lwa_holders TYPE swhactor,
              lt_users TYPE STANDARD TABLE OF ty_users,
              lwa_users TYPE ty_users,
              v_len TYPE i,
              v_bname LIKE ztest_users-bname,
              num_lines TYPE i.
*Read values assigned to the rule criteria
  swc_get_element ac_container 'org_agent' org_agent.
*Get the superior
  SELECT SINGLE * FROM ztest_users INTO CORRESPONDING FIELDS OF lwa_users
  WHERE bname = org_agent.
IF NOT lwa_users IS INITIAL.
    REFRESH lt_holders[].
    lwa_holders-otype = 'US'.
    lwa_holders-objid = lwa_users-zsuperior.
    APPEND lwa_holders TO lt_holders.
    APPEND LINES OF lt_holders TO actor_tab.
  ENDIF.
  DESCRIBE TABLE actor_tab LINES num_lines.
  IF num_lines IS INITIAL.
    RAISE nobody_found.
  ENDIF.
ENDFUNCTION.
3. Now assign the function module on the rule.
Goto PFAC_INS  to create the Custom Rule.
In the rule definition category select Agent Determination: Function to be executed.
In the Function module field give the name of the function module created (ZTEST_FIND_SUPERIOR).
Check the Terminate if Rule resolution without result check box.
4. Create a container element ( org_agent)for the agent or user which will be passed to the function module.
Type:
WFSYST-AGENT.
properties: import.
5. Test the Rule by the Simulation button on the application toolbar.
Enter the user name in the Container Element value section and press enter.
It displays the name of the superior for the agent/user and the Agent Found is displayed in Green color.
Now you can use this rule in your Workflow definition.
Thanks,
Reshmi
