When Sub module Customer & Vendor set to None under Ledger period setup then system will restrict users to enter any transactions for Vendor & Customer (Accounts receivable & Accounts Payable) but same will be allowed from General Ledger module.

Whereas in 2^nd case, when sub module Project is set to None under Ledger Period setup then system will restrict users to enter transactions from both modules Project and Accounting management & General Ledger module.

In comparison with above two scenarios customer wants to understand why there no uniformity in the functionality where Project is also an sub module and it should allow user to enter transactions from General ledger module else same logic should applicable to AP & AR modules as well.
