Hi, cleaning up records ‘within’ a time period doesn’t seem possible when there is a set parameter for ‘Days Before Current Date’. Maybe you will have to handle this in the database as a data repair. 

When you run the Cleanup of Inventory, the system will only consider records where the on hand quantity is 0 for the number of days, ‘Days Before Current Date’ entered.  It will only cleanup records that meet that criteria.

At a tangent to this. When should you be clean up inventory records? What are the disadvantages? We are currently writing a report that uses inventory part in stock for serial tracked items.
