Hi Prashant,
I worked on your code and found that the exception is thrown in the standard FM..
CALL FUNCTION 'SKWF_NMSPC_IO_FIND_BY_ADDRESS'
      EXPORTING
        url   = l_url "parent url
        appl  = wbmr_c_skwf_appl_name
      IMPORTING
        io    = g_parent_loio
        error = l_error. "is also set, if l_url not found !
Reason:
I named my BSP application Z_MIMEUPLOAD I was getting dump when ....
In layout and in OnInputprocessing I used ZTEST_MIMEUPLOAD instaed of Z_MIMEUPLOAD
The dump disappered as soon as I corrected the BSP application name everywhere in the application.
Please check the url and application name everywhere in your code.
Also replace the code:
CONCATENATE 'http://siildev.siil.com:8001/sap(bD1lbiZjPTc3Nw==)/bc/bsp/sap/zprbsp_002/' wa_file into
By this:
CONCATENATE 'http://siildev.siil.com:8001/sap(bD1lbiZjPTc3Nw==)/bc/bsp/sap/zprbsp_002/PAGE_NAME' wa_file into
That is add page name to url in layout.
I am not sure what is hapening in your code but this is what I found.
Hope it helps you.
Regards,
Anubhav
