Parts & BOMs - Something I am missing?

[janb]

webERP version 4.12.2
Have done some patches as well from svn where necessary.
(but don't have the rev. for you just now)

Edit:
..sorry, have not checked the MRP report yet, planning to do that later today or maybe to morrow.
I made a new test company yesterday with some relevant data to make it easier to check but have to do some serious thinking/testing to get this right.

Btw. I have written a script that seems to work quite well giving me shortage for both single items and parents.
I haven't tested it with all possible variations for qty's , the challenge is to ensure qty's is split where it's on the "edge" for build / on hand where qty pass zero within a parent with childs.
It seems i can't send you an PM or e-mail?
Thought maybe you would be interesting having a look? It's quite different from the original script without temp tables.
