Saving as a draft allows you to access and finalize the bank statement at a later time or date. For example, if you need to check information or wait for an approval before finalizing, you can save the bank statement as a draft and then call it up later and subsequently finalize it.
Define at least one transaction row in the Bank Statement Details window and choose the Save Draft button.
A draft bank statement is added to SAP Business One and can be accessed through the Bank Statement Summary window, and viewed by running the Bank Statement Information report.
