23.1.4

In Visual Shop Orders Planning, the Material Material Availability Summary chart shows (4) orders with a shortage, and the same part is short on these four orders.

My Material Lines Availability chart is filtered from the Material Availability Summary chart.

When grouping by Material Line, I can see each instance of this part on its four shop orders. The Remaining Quantity on these orders are 30, 30, 20, and 20 for a total of 100.

When grouping by Part, though, the Remaining Quantity shows as 30 not 100. Why is this not showing 100 as the Remaining Quantity for this part on this date?
