Negative Inventory with ckecked option 'Block Negative Inventory'
Does somebody know why B1 (2005A SP01 PL31) lets me issue goods for production that end up in a negative inventory although I have checked the option 'Block negative Inventory'?

The "Manage Inventory by Warehouse" setting affects a number of different functions. As indicated, it means that negative inventory may be blocked by warehouse, rather than all warehouses added together. Similarly, warnings about inventory falling below minimum and the item availability check will refer only to the quantity in the specific warehouse, instead of the combination of all warehouses. In addition, this setting causes the item cost, minimum, maximum, and required fields to appear at the warehouse level rather than for the item as a whole.
I haven't worked much with MRP, but my understanding is that it considers the total quantity of all warehouses, as well as open SO's and PO's for all warehouses, regardless of this setting.
