Open Order quantity?

Hi everyone,

I have a question about stock overview.

When you enter transaction MMBE and enter a certain material, you will see, as a result, the stock overview for that material.

When you click on 'Choose (F2)' while selected the total unrestricted use quantity, a new window will appear. In this window some (calculated) stock quantities will be shown.

One of those items shows the 'Open Order qty'.

Does anybody has a query or FM which will give me this 'Open Order quantity', so I can use this value in another program/report.

Does anybody know how to calculate this quantity (which tables, fields, ... )

Many thanks in advance.

Guy.
