Is there any possibilities to lock the Received in and Paid from (in the Receipts & Payments form)
to a certain Cash Account unless changed when required and without going to the Suspense
Example
Yes. Set this under Form Defaults. See Set form defaults | Manager. Be advised, however, that you can only set one account for both for receipts and payments, since those transactions share the same form. If you typically pay from one account and receive in another, you will have to choose which becomes your default.
Likewise, you can only choose Receipt or Payment as the default transaction type.
Got it Thank You
