To perform any Transactions through ABAP coding we have BAPI, Function Module or Class-Methods, But for few Transactions there are No direct  BAPI, Function Module or Class-Methods, In this situation a developer chooses “BDC Call Transation Method” to Update the specific Transaction.

where as from Web Dynpro we cannot directly run the BDC.

A simple solution can execute BDC through Web Dynpro.

Below are the details of “How to Execute BDC in Web Dynpro” :

step 1)  Create Recording for a specific Transaction using ‘SHDB’ and Transport the recording to a Executable Report Program .

step 2)  Write the BDC coding for the Recording using CALL TRANSACTION METHOD. ( note : Always use MODE : ‘N’ )

             Example        CALL TRANSACTION ‘MM01’ USING IT_BDCDATA MODE ‘N’
                                                         
UPDATE ‘S’
                                                          MESSAGES
INTO IT_MESSTAB_tmp.

NOTE :   Do not place any output screen Results, like ‘write’ statements, it will give a short dump while we execute through Web Dynpro .

step 3)  To exchange Data between Web Dynpro and Report Program we can export the result to Memory ID and Import the data in Web Dynpro from Memory ID.

               Example  Export IT_MESSTAB from IT_MESSTAB_tmp TO MEMORY ID ‘KRANTHI’.


step 4)  Create a Web Dynpro Component and where ever it is necessary to trigger a BDC, SUBMIT to the Report Program using the below syntax.

              Example :    submit ztest_mm_demo2 with material_id = lv_matnr and return.

NOTE: here Material_ID is the Parameter of the Report Program, I am passing a Material_ID from WebDynpro to Report

       Program.

step 5) After executing the Report Program which contains BDC the Result is Exported to a Memory ID from Report Program, we have to Import the Result from

           Memory ID using the below Syntax .

               ExampleImport it_messtab to it_messtab_tmp from memory id ‘KRANTHI’.

This is the simple solution how to Run the BDC through Web Dynpro.

Below I am placing a sample code for Creation of a Material using Web Dynpro & BDC.

    I think this is the first blog that starts with “Very useful tip.”.

    After seeing the entry in activity feed, I thought that it is a comment to existing blog.

      If we program the BDC in Function Module or Class Methods, when we try to run the Function Module or Class Methods through webdynpro it leads to short dump, as webdynpro will not work with the Parameter ID’s . when you record a transaction the recording will contain the parameter ID’s hence it leads to short dump. where as here we are submiting the control to a Report Program and Returning the Control to webdynpro.

        hmm. I cannot understand why you should get a dump. Parameter IDs are stored on the application server. The backend of the webdynpro runs on the appserver. I’ve run BDC through function modules starting a new task without difficulty.

        What is the nature of the dump you get? I want to get to the bottom of this!

        (I’m so old that I used to do BDC by hand… before you could record them…!)
