Left-click on the button Open quantities on the horizontal toolbar of the main window to display only the requirement quantities for which there is no purchase yet. Open requirement quantities are highlighted in red.
Select a supplier from the list at the bottom right. New, embeddable columns appear in the list of requirement items and only the items that the selected supplier can supply.
Enter the quantity (packaging units) or quantity (content unit) of the item you wish to order from the selected supplier in the corresponding column. Click on Adopt values to adopt the value of the open quantity/number as the order quantity. Note: As long as no supplier has been selected, the columns Quantity and Quantity do not appear.
If the ordered quantity corresponds exactly to the demand, the column Open turns white. If there is a shortage, the column remains red; if there is a surplus, the column is green.
