When you use the Wizard to set up the number sequences for your new company, you will likely run into issues with duplicate numbers when you are entering transactions into the application, unless you take the appropriate actions during setup. To avoid this issue you will need to go into the each module parameters and find all references that the Wizard has setup with duplicate number sequences and change the format, so they are unique. This is time consuming so the request is to improve the number sequence framework so that it does not create issues when creating transactions.
