I am working with an integration with GP in C# using GP Webservices.
I'm building InventoryAdjustment objects with InventoryAdjustmentLines and supplying quantities from our product information in SQL. However, sometimes these Adjustment quantities are negative. When I run CreateInventoryAdjustment using a negative quantity in my InventoryAdjustment object I get an error:
Quantity must be greater than 0
However, I can post negative adjustments through the GP UI.
