MRP net results always out by the internal allocation quantity

It seems in Enterprise management when we run MRP and there are internally allocated quantities our net result is always out by this number.

Has anyone experienced this and how can we resolve.

An example is shown below based on client data

  

On the Component Item when we calculate manually

  • we need 36 items
  • we already have 1 on hand – Column D  (takes us down to 35 needed)
  • we have 1 on work order already – Column F (takes us down to 34 needed)

 

** MRP is suggesting we need 35 instead of 34 because of the 1 internal allocation. That is the issue.
