Hello Priyank,

You will have to a small work around to achieve this.

1. Get a list of all the file names in an internal table (file names) typically read from some Directory ..

2. Loop on the internal table (file names) and Upload them to the corresponding internal tables (data).

Sample Code :

 *Step 1. Read all the filenames by doing a Directory Listing 

 CALL METHOD cl_gui_frontend_services=>directory_list_files
   EXPORTING
     directory                   = dir
     files_only                  = 'X'
   CHANGING
     file_table                  = it_pfiles
     count                       = count
   EXCEPTIONS
     cntl_error                  = 1
     directory_list_files_failed = 2
     wrong_parameter             = 3
     error_no_gui                = 4
     not_supported_by_gui        = 5
     OTHERS                      = 6.
* Step 2: Loop on the file names to upload each one  
 LOOP AT it_pfiles INTO wa_pfile.
   WRITE wa_pfile.
 ENDLOOP.

Since the file names are dynamic, you can concat them into a string with a delimiter and pass it on to the batch file as an input parameter.

And you decipher the filenames in the batch file and continue with the processing.
