Here is an outline of how to create an inventory adjustment in the Inventory module for Microsoft Dynamics SL, formerly known as Solomon accounting software.
In the Inventory module, choose Adjustments from the Input section. In the Adjustments screen, down in the Detail area, click in the Inventory ID column and press F3. The Inventory Item List screen opens. Select the item you want to adjust and click OK. Under the Quantity heading, you can enter the adjustment that you want to make. Make sure that your Quantity Control matches your Quantity Total, and that your Cost Control matches your Cost Total.
