When I run WO-L-F and select all items, the report does not list all bill of material items.
 
Also I have been finding that some items on the BOM are skipped and not shown on the report, even when a shortage exists.
 
I use this report on specific work orders or ranges of work orders.  I do not use any other filters.
 
The work order shortage report would be very useful for our business.  But I currently don't trust that it gives me complete answers.

More data --
If I select "All" instead of "Shortages" and answer "N" to "Rebuild Stock Status Fields", then DBA prints the full BOM.
 
If I select "All" and answer "Y" to "Rebuild Stock Status Fields", then DBA does not print the full BOM.
 
Is this what I should expect?  I can now get a report that shows what I need, but it took some futzing to get to this point.
