i am working on creating PO's by reading data from a text file. I need to implement fail safe logic in it, which is to make sure this program uploads all the records in the text file successfully. For example, i have 1000 records in my text file and while running the upload program if the program times out while creating the 500th PO or if SAP is down at that time, then we have 499 PO's created and 501 yet to be created. But if we run the same program again, we will generate duplicate PO's for 499 again. I want to avoid this kind of problem.
How do i implement this idea?
Kindly guide me on this.
