When the first record of your script is uploading to SAP successfully, but all other records are failing
In some instances, SAP may populate certain fields with information from the previous record causing the script to fail.
1. Open your script
2. Navigate to the Map tab
3. Change "Renew session after (n) transactions" to have a value of 1
4. Save and retest
Using Renew Session will ensure that this data is not present, allowing other records to run successfully.
