Transaction group 405 (Wt Avg Update Writeoffs) errors in Accounting Line

Hi,

We are in the process of upgrading PSoft FIN from v8.9 to 9.1. As part of the upgrade document, verified the "Accounting Line Errors" ( Cost Accounting --> Invt and Mfg Accnt --> Create Accnt Entries --> Accounting Line Errors), and found bunch of errors with error: " No Account Distribution Rule" for Transaction Group: 405 (Wt Avg Update Writeoffs), though this transaction group does exist in the system.

Can any one please let us know what this error refers to, and how to resolve it?

Thanks in advance,

Vijaya
