There may be a scenario where once the AR Receipt is printed and listed, the user would want to restrict further editing to that particular Receipt entry. Using a simple feature in Sage 300 ERP users can restrict modification to the AR Receipt once it is being printed
New Stuff:  Miscellaneous Payment Feature in SAGE 300 ERP
To achieve this User needs to navigate to A/R Setup–>Options–>A/R Options

There is an option called “Allow Edit After Receipt Printed” in the Transactions tab. If this option is not checked, then the user won’t be able to make any modifications in the receipt after it is printed. You can refer the below screenshot where all fields are being disabled for the Receipt that is already printed. Now users will not be able to make any modifications in the receipt.

Sage 300 ERP also provides a notification through the message, which warns the user that the receipt is non-editable


 
 
 
 
 
 
 
Alternatively, if the user selects the Check box “Allow Edit After Receipt Printed” then the user can make modifications in the A/R Receipt.


Thus, using a simple configuration setting you can control the editing of the Printed receipts. Also, this feature can be changed at any point of time.
