Hi Jitendra,
First.... Yes, is such as for doing a strong transaction. The backend is SAP R2.
The application stores all the information of the day to be synchronized at the end of the day.
I use a RFC custom. The app work all time offline mode.
This RFC has 2 fields as input parameters and 2 tables. A table to raise the sales information (input) and another table for the results (output).
In small tests, an error is never obtained. But to make a real test, with greater volume of information, the application generates the exception.
Thanks for your help.
