The Merge many function under Vendor/Maintenance/Merge is used to merge multiple purchase orders to the same supplier.
- Filter the list so that the purchases to be merged are shown in the list, most often filtered as a minimum on the Account field i.e. per supplier
- Place the cursor on the purchase that all purchases for this supplier should be grouped into
- Select the Merge button , type the word start and select the OK button
- All purchase lines from the other purchases you had in the filter are now moved to the purchase you had selected and the purchases are deleted, so there is now only one total purchase.
