Change a reservation by dimensions

When you change reservations by dimensions, you can either specify that an existing reservation should be for specific dimensions or you can change the dimensions of the reservation.


When you reserve a quantity of an item, you can only reserve on dimensions that are active for the item.

  1. Open the Reservation form by following the preceding guidelines, and select the line where you want to change the dimensions of a reservation.

  2. Click Inventory > Dimensions display and in the Dimensions display form, select the check boxes for the dimensions that you want to either specify or change.

    Lines are displayed on the Overview tab in the Reservation form for each of the existing dimension combinations of the order line.

  3. Select the line for the dimension combination where you want to either reserve a quantity or change the reserved quantity.

  4. Change the quantity in the Reservation field.


When you display a specific dimension combination in the Reservation form and then edit or enter a quantity in the Reservation field, the reservation is locked to the selected dimensions and the reserved quantity is dedicated to these dimensions. You can unlock dimensions by clearing the check boxes under Lock reservations.

If Primary stocking is specified for an item via the product dimension group, the dimension is always locked and it cannot be unlocked.


A customer calls with a request concerning a load of bricks that they have ordered from your company. The customer wants to make sure that the bricks are reserved from the same batch as the previous load that they received. When checking, you observe that the bricks are reserved automatically with no batch number specified on the sales order line so you need to make sure that the reserved quantity has the correct batch number and that the reservation is locked with this batch number.

  1. Select the sales order of the ordered brick load in the Sales order form and open the Reservation form.

  2. Apply one of the following methods depending on whether the bricks have been automatically reserved with the correct batch number or not. If the batch number is correct, you just need to lock the batch number reservation to ensure that the batch number is not changed by an automated process. To lock the batch number, do the following:

    1. Select the reservation in the Reservation form.

    2. Click Inventory > Dimensions display.

    3. Select the Batch number check box, and click OK.

    4. Select the Batch number check box under Lock reservations.

  3. To change the batch number dimension of the reservation, do the following:

    1. Click Inventory > Dimensions display, select the Batch number check box, and click OK.

    2. Select the existing reservation in the Reservation form, and change the quantity in the Reservation field to zero to cancel this reservation line.

    3. Select the line with the batch number dimension that the customer requested and enter the quantity in the Reservation field.
