I would like to update a large amount of records, and want to run multiple batches of 500 records or so at a time, simultaneously. How can I do this?
What you will want to try is opening a maximum of three Winshuttle Studio sessions at one time. Then, you will want to utilize Background mode option from the run screen (image below). Make sure to check this in all of your open instances of Studio that you will be running simultaneously.
You will also want to make sure and change the start/end rows for each script (also shown in image below) to make sure they run correctly (ex. 1st script starts at row 2 and ends at row 200, 2nd script starts at row 201 and ends at row 400, etc). For the first script you try to run, you may get an error message but all you would need to do is try running it again and it should work.
We would not advise running more than three batches of scripts at a time, as this could potentially overload your SAP system. Try starting out with three and then also use the "renew session option" (image 2 attached) and enter 100 in this field for each script. This will tell the script to run 100 records at a time and restart the SAP session connection each time.
