Long-time Sage 100/Aatrix user attempting to file my first Acumatica-based 941. Acumatica downloads the data, but on Verifying Data I receive the following error: The EIN in the AUF does not match the specified EIN for the user. I have verified with Aatrix our EIN is correct (logged in and verified on the Aatrix website and verified with an Aatrix tech).
Acumatica is passing either the wrong EIN or possibly a masked EIN (e.g., dash after the second digit as is common) or possibly a blank. I have searched high and low and found no instances of errors or blanks in Acumatica setup.
Anyone encountered this error and have a fix?
