Question

hi,

give me the exact steps to proceed with the above.

Answer 1

Hi Saritha,
Your question is not clear to me but I am assuming your queestion like this
"Providing choice for user for using either call transaction & Session method for uploading data"
When you generate the BDC (Batch Data Communication options define the processing mode for a batch input session) program with SHDB, you can remove a lot of unwanted fields by copying this customize abap include program.  It allows you to execute the BDC program immediately without filling up those SAP generate fields.  To run background, just run it as a background job.
Execute BDC immediately by replacing the include BDCRECX1

***INCLUDE ZBDCRECX1.
When you generate the program using SHDB, you can replace it
with this if you want to execute it immediately without having
to process it using SM35.
During testing you can used the original include.
For example,
include zbdcrecx1.   "After test
include bdcrecx.     "Before test
