The reason why the bank statement item (BST-item) is in status 3, is to give the user a warning that the item should be reviewed/checked. 

For example, if there are duplicates (two) bank statement items (BST-tems) with the exact same amount, one 

of items will get status 3 to be reviewed that it is not the same payment being performed twice.

 

If all is correct, the user can manually forward the bank statement item to status 4 using the menu option 'Confirm Bank Statement item (St=4)'.
