In Sage 300, fiscal periods are locked separately for each transaction-oriented Sage 300 program.
The system checks the status of a fiscal period for Accounts Receivable when you enter certain dates in Accounts Receivable transactions. It also checks the status of the fiscal period for Bank Services when you add a receipt or print a refund check.
If the period is locked for Accounts Receivable, you receive a warning, an error message, or no message, depending on the setting for the Locked Fiscal Period option on the Options tab of the Company Profile screen, as follows:
Important! Generally, you should lock a period for Accounts Receivable, Bank Services, and Accounts Payable at the same time, to avoid this situation.
Important! You should create and post General Ledger batches for outstanding Accounts Receivable transactions before locking a period for General Ledger.
