Master planning / on-hand issue (net requirements)

That is only a filtered version, so this means you need to look at what is pulling it all and when, you are at a lower level so you are showing a subsection of the whole picture. Very difficult to troubleshoot from here, you need to dig into the details of the net requirements I am afraid. The full run shows you everything, which is interesting as it starts with a negative on hand when you have it on hand. Not seen this before I am afraid.
