Hi Rohit,

If you wants to just execute the ABAP Program from Web Dynpro ABAP you can use the following Code

SUBMIT ZXXXX with par1 = 'value 1' with par2 = 'value 2' and return.

If you wants bring the values back to Web dynpro abap from ABAP Program you can use the following code.

SUBMIT ZXXXX EXPORTING LIST TO MEMORY.

  Use the FM to retrieve from memory.

CALL FUNCTION 'LIST_FROM_MEMORY'

      TABLES

           DATA = LT_DATA

      EXCEPTIONS

           NOT_FOUND  = 4

           OTHERS     = 8.

But please make sure the report is not directly calling any screens or BDC in 'A' or 'E' mode.

Hi Rohith,

If you have parameters to be passed from NODE,.

• Read the values from the node into local work area and then pass as parameters to program

               data ls_data type wd_this->element_MY_NODE.

               data lo_node type ref to if_wd_context_node.

               data lo_element type ref to if_wd_context_element.

                    lo_node = wd_context->get_child_node( name = 'MY_NODE'  ).

               lo_element =  lo_node->get_element( index = 1 ). " Get the record from node using index

               lo_element->get_static_attributes( importing static_attributes = ls_data ).

Option 1:

     " Now pass the values to the program call, note this call should be made from a method of assistance class

          submit zprogram with par1 = ls_data-att1, etc.

Option 2:

          Create a transaction for your program , ex: ztcode

           now call the ztcode by passing the parameters from Webdynpro and skip first screen.

          Please search SCN, where many threads available to answer on "calling tcode from webdynpro"

          Refer the link: Calling Transaction Codes through Web Dynpro Application

Hope this helps you.
