Function module for finding related IDOCs of a document

Question

Hi All,
I have a requirement where the inout will be shipment numbers. The expected output is the list of all the IDOCs that are related to the shipments. I know that this is a replica of the WE09 functionality but the users will not have access to WE09 and more over WE09 takes a long time to give this result.
My expectation is someting like the relationship in the "Services for objects2 that we have in the document which will give this detail very quickly.
I know one function module (WFMC_PROTOCOL_GET) which will give the list of outbound IDOCs if we know the output type  and the shipment number. Also there is another function module GOS_EXECUTE_SERVICE which will do very similar to the servie for objects. But I need to know exactly the class or function module which will give me the relationship output alone so I can use this for further processing.
Also kindly let me know if there is some other standard way of looking  at this requirement.
regards,
Vijay V

Vijay,
You can use FM  'DRB_NEIGHBOURS_GET' for the required functionality . Here is sample code :
DATA : L_BORIDENT  TYPE  BORIDENT ,
        T_RELATIONS TYPE TABLE OF BORIDENT .
  L_BORIDENT-OBJKEY = Delivery_no .      "Document no
  L_BORIDENT-OBJTYPE = 'LIKP' .          "Object type e.g. LIKP , BUS2025 
    CALL FUNCTION 'DRB_NEIGHBOURS_GET'
      EXPORTING
        BORIDENT           = L_BORIDENT
      TABLES
        T_RELATIONS        = T_RELATIONS.
Linked Idoc type will be in table T_RELATIONS with OBJTYPE value equal to 'IDOC' .
