Incorrect Committed Quantity Item Master Data Item Data Tab

Hi All

I am having an issue with the Quantity Committed data not being correct for a handful if Items.

All of the Items in question are in their own Item group.  This group was set up as FIFO costing where the rest of the system is set up as

Moving Average.  We would like to change FIFO to Moving Average as this was done in error.

The Quantity committed seems to be quite a bit higher than the actual Open Orders indicate.

I have checked the various Item Unit of measures,  that is Inventory Uom, Sales Uom and Purchase Uom and all are set to 1

The Items are used on Sales BOMs

And Order is Entered,  Then pushed to a Delivery Note, and finally pushed to an Invoice.

Currently the customer is running on SAP B1 9.02.250 pl15

Any input would be greatly appreciated!

Thanks in advance
