Thank You Hareesh and Nabendu for the response.
I did try sending the request message with date format as YYYYMMDD, and message got processed successfully and we received the response message as well from ECC.
But the problem is in response message it shows" Error in Fetching TI entries" where as it should have sent the values available for the particular date we have sent in request message.
However i am checking with ECC team, as BAPI accepts only YYYYMMDD format.
Will keep you posted on this.
Thanks,
Jane
