Examples for using function modules and BApis.

Former Member — Wed, 07 May 2008 09:53:00 GMT

My Dear FRNDS,

I am very new to ABAP. And I have read the documentation for function modules but i am not that clear to practice them.So I would be very happy if u people share a little bit of ur experience with me.

Please provide me some examples of all the use cases in function modules and specially exception handling.

Frnds, i am going to work with bapis so i feel practicing function module will give me a edge.

and please tell me after calling a BAPI FM why we have to perform 'BAPI_TRANSACTION_COMMIT' and 'BAPI_TRANSACTION_ROLLBACK'.

.Ur efforts will be greatly rewarded.

thx,

reshali

Most of the FMs have a return parameter, that specify that the FM call is successful or not. IF it is successful then call 'BAPI_TRANSACTION_COMMIT' to have a database commit or if it is not successful then revart the changes that are already done in database by 'BAPI_TRANSACTION_ROLLBACK' FM.

Now, both this FM calls generally behave like a normal database COMMIT or ROLLBACK. Only difference is that by BAPI you can update the database of a remort system so you need to commit/rollback in that syste. that is why we use 'BAPI_TRANSACTION_COMMIT' or 'BAPI_TRANSACTION_ROLLBACK' instead of normal commit/rollback.

Example:



        CALL FUNCTION 'BAPI_FIXEDASSET_OVRTAKE_CREATE'
          EXPORTING
            key                 = la_key
            testrun             = l_testrun
            generaldata         = la_generaldata
            generaldatax        = la_generaldatax
            inventory           = la_inventory
            inventoryx          = la_inventoryx
            postinginformation  = la_postinginformation
            postinginformationx = la_postinginformationx
            timedependentdata   = la_timedependentdata
            timedependentdatax  = la_timedependentdatax
            allocations         = la_allocations
            allocationsx        = la_allocationsx
            origin              = la_origin
            originx             = la_originx
          IMPORTING
            assetcreated        = la_assetcreated
          TABLES
            depreciationareas   = li_depreciationareas
            depreciationareasx  = li_depreciationareasx
            cumulatedvalues     = li_cumulatedvalues
            postedvalues        = li_postedvalues
            transactions        = li_transactions
            return              = i_return.

IF NOT i_return[] IS INITIAL.

        CLEAR: wa_return,
               wa_error_file,
               l_message.


        LOOP AT i_return INTO wa_return.

          IF wa_return-type   = 'S'.

            wa_error_file-type = wa_return-type.
            g_no_load = g_no_load + 1.

            IF l_testrun <> 'X'.

              CONCATENATE text-009 la_assetcreated-asset
                  INTO l_message.

              CLEAR: la_assetcreated.

              CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
            ELSE.

              l_message = text-064.
            ENDIF.

            EXIT.
          ELSE.

            IF l_message IS INITIAL.
              CONCATENATE l_message wa_return-message INTO l_message.
            ELSE.
              CONCATENATE l_message wa_return-message INTO l_message SEPARATED BY ','.
            ENDIF.

          ENDIF.

I have already given a example above. Another simple example is as follows:


REPORT  Z34332_BDC                              .

data: i_MATNRSELECTION type table of BAPIMATRAM,
      wa_MATNRSELECTION like line of i_MATNRSELECTION,
      i_MATNRLIST type table of BAPIMATLST,
      wa_MATNRLIST like line of i_MATNRLIST,
      i_return type table of BAPIRET2.

wa_MATNRSELECTION-MATNR_LOW = '000000000000000001'.
wa_MATNRSELECTION-MATNR_HIGH = '000000000000000055'.
wa_MATNRSELECTION-SIGN = 'I'.
wa_MATNRSELECTION-OPTION = 'BT'.
append wa_MATNRSELECTION to i_MATNRSELECTION.
clear : wa_MATNRSELECTION.


CALL FUNCTION 'BAPI_MATERIAL_GETLIST'
 TABLES
   MATNRSELECTION                     = i_MATNRSELECTION
   MATNRLIST                          = i_MATNRLIST
   RETURN                             = i_return
          .

clear: wa_MATNRSELECTION.


write: /'Material'.
loop at i_MATNRLIST into wa_MATNRLIST.
write: / wa_MATNRLIST-MATERIAL.
clear: wa_MATNRLIST.
endloop.

What type of help u need in functional module?

Go thru this link

http://www.planetsap.com/LIST_ALL_BAPIs.htm

BAPI_TRANSACTION_COMMIT

Execute external Commit when using BAPIs

This method executes a COMMIT WORK command. It is required for

transactions developed externally to the R/3 System that change data in

the R/3 System via BAPI calls.

When you call BAPIs in your program that change data in the R/3 System,

afterwards you must call this method to write the changes to the

database.

COMMIT WORK

The statement COMMIT WORK completes the current SAP LUW and opens a new one, storing all change requests for the currenta SAP LUW in the process

there are some FM that we use for creating trasaction . for example FM : that use for creating production order . if you execut the FM , the system will not create any data in the system so you need to excute the FM : BAPI_TRANSACTION_COMMIT to commit that creating the production order .

in case of commit work, that is a syntax in abap program . if you use this syntax after you insert ,update or delete table in the sap ,system will do it immediately otherwise the system will do it after execution is complete.

ROLLBACK WORK.

for confirming or undoing database updates. COMMIT WORK always concludes a database LUW and starts a new one. ROLLBACK WORK always undoes all changes back to the start of the database LUW.

Raj.
