There is a handy report called the critical on-hand inventory report that you can use as a check for items that might have got below a minimum. This will let you check if there is something ordered which will give you an indication that you might need to investigate the replenishment of the item.
You will see in the video that the reports runs off the coverage settings so if you have an item on the report that is below a min and you were expecting inventory then you might need to investigate the item for example the inventory was put in the wrong warehouse or you didn’t have coverage settings setup.
Here is a quick overview.
