Acct/Per ___ __  ____ ____ ___Autopost#____: 

This error indicates that one of the general ledger accounts to which the amounts from this invoice will be posted does not have a valid account period record set up in the general ledger.  Sales are posted by product line and each product line stores autopost numbers which indicate the general ledger accounts that will be updated when the item is sold.  Each of the accounts that will be updated by the Sales Posting Program must have an account period record set up in the year, period, division and department that the sales will be posted to.  To fix this problem you should contact the individual responsible for the set up and maintenance of your general ledger account structure and have them correct the problem.  Please refer to the General Ledger documentation for a complete description of autopost numbers and a list of the autopost numbers which are used by the Sales Posting programs.
