I can see the same error message on the same date as the sync error in Bill.com. And it repeats every day with a couple of other error messages. INVALID_FORMULA_FIELD {"message":"Your formula has an unrecognized field in it. Please go back and correct the formula and resubmit."}

Checked and there were no errors. This has been super confusing to try to figure out because we haven't made any changes that would impact the integration with Bill.com and even their support team couldn't determine the issue.

Not that I'm aware of… things were still working properly after the last upgrade. I'm wondering if uninstalling the integration and reinstalling it would be the best option at this point.

@Tigran Shahnazaryan Yes, the POs are being created in NetSuite; however, they are not syncing to Bill.com. So, when I try to enter the vendor bill in Bill.com, the items from the PO are not in Bill.com to receive. I have to manually enter them to align with what's in NetSuite.
