Automatic merging of duplicates of the transaction. The widget glues duplicates of transactions of one contact. As soon as a duplicate appears in the system, the widget combines the transaction data. When combining in the final transaction, all non-empty fields in doubles are filled in, if the same field is filled in doubles, a value is selected from the settings you selected.
In the settings, you can choose which way to combine the transaction:
In the direction of the senior transaction - all duplicates will be combined into a transaction created earlier than others
Combining in order in the block - transactions will be combined by priority in the block, the lower the priority.
