Problem while creating generic function module

Question

Hello experts,
The master data 0VENDOR_ATTR is extracted using function module MDEX_VENDOR_MD. I have to create a generic data source based on the function module MDEX_VENDOR_MD. My code does not identify the data source name while debugging.
Below is the original code from MDEX_VENDOR_MD:
Check InfoObject validity and set IO-dependent parameters
    G_TAB1_FLG =  G_TAB2_FLG =  G_TAB3_FLG =  G_TAB4_FLG = ' '.
    CASE I_CHABASNM.
      WHEN '0VENDOR'.
        G_TAB1_FLG = 'X'.
        G_TABLENAME = 'LFA1'.
      WHEN '0VEN_COMPC'.
        G_TAB2_FLG = 'X'.
        G_TABLENAME = 'LFB1'.
      WHEN '0VEN_PURORG'.
        G_TAB3_FLG = 'X'.
        G_TABLENAME = 'LFM1'.
      WHEN OTHERS.
        IF 1 = 2. MESSAGE E009(R3). ENDIF.
        LOG_WRITE 'E'                  "message type
                  'R3'                 "message class
                  '009'                "message number
                  I_CHABASNM           "message variable 1
                  ' '.                 "message variable 2
        RAISE ERROR_PASSED_TO_MESS_HANDLER.
    ENDCASE.
When I debug 0VENDOR_ATTR, In above code, it identify the data source 0VENDOR (i.e. I_CHABASNM = 0 VENDOR)
My code :
CASE I_CHABASNM.
      WHEN 'ZDATA_SOURCE'.
      WHEN OTHERS.
        IF 1 = 2. MESSAGE E009(R3). ENDIF.
        LOG_WRITE 'E'                  "message type
                  'R3'                 "message class
                  '009'                "message number
                  I_CHABASNM           "message variable 1
                  ' '.                 "message variable 2
        RAISE ERROR_PASSED_TO_MESS_HANDLER.
    ENDCASE.
I created above data source ZDATA_SOURCE in RSO2 by giving function module  ZMDEX_VENDOR_MD (copy of original function group to Z group with few modifications in ZMDEX_VENDOR_MD). Every thing is OK, but while debugging, the cursor leads to WHEN OTHERS clause in above CASE statement and the program terminated with log(i.e., the program does not identify I_CHABASNM = ZDATA_SOURCE).
When I see 0VENDOR_ATTR in RSA3, there is no associated function module MDEX_VENDOR_MD is visible. What could be the reason?
your suggestion is really helpful...
Thanks in advance,
Zak.

Hi Zakir,
try this........
<CASE I_CHABASNM>----
-<WHEN '0VENDOR'>---
case I_Datasource
when 'datasource name'.
