I have an example, where order is created with multiple line items. Some line items have different payment terms. They are not copied from payer master data or sold-to master data.
I have done below validations:
1. I have checked for manual change of payment terms in order for the specific line item
2. I have looked into pricing condition records with payment term for the line items
3. I also don't see any custom changes around ZTERM field
Could you please let me know if I am missing any other checks?
