We are getting errors when importing orders into Order Entry from EDIPAC.

Examples:

Invalid data 'CSAC86553711' for field called 'Det-Item Number' of record 114.
Item number CS-AC-86553711 does not exist on price list CNH.

Invalid data 'CSAC86729282' for field called 'Det-Item Number' of record 120.
Item number CS-AC-86729282 does not exist on price list CNH.

When it is done, there is a message stating that no records were imported. We have never had these errors before updating to 8.1C (100208).

Do the items exist on the price list CNH?

Yes, the items do exist on the price list CNH.

In the company profile what option do you have for 'Use base price list if not found'?
In your import order template, do you have either H-Price List or D-Price List selected? If so, which one has the CNH price list value? If not, is this the value defined on the customer?

There are many options that could possibly affect this. That being said, those validation messages should not appear if the item number has correctly been defined on an alternate price list.
