Re: procurement scheduler and nested BOMsby
The proposed methods are to start at the bottom of BOMs and work up, or to priorities the order points so that presumably you do the high level items first so when you get to the little ones you have already created the requirement.
I am unconvinced either of these will work perfectly in all complicated BOM situations, repeating the process until there is nothing left to do will always work exactly as it does now.
Search the bug reports, this exact scenario is covered in there with a patch which from memory was rejected as it was too complex.
+1 this is a key requirement for a professional MRP system.
The scheduler that computes order points and creates the manufacturing orders works OK, but for nested BOMs it needs to be run multiple times. Is there a way of triggering a re-run if there were things found during processing that created new requirements? for example, if we want to build a house, which is made up of a roof and 4 walls, the roof being made of tile and the walls of bricks the BOM structure might be like this: house (1) roof (1) tiles (100) wall (4) bricks (1000 when we procure a house, it will create manufacturing orders for 1 roof and 4 walls, but these can't be produced because they will be waiting raw materials. Running the scheduler a second time will procure the tiles and bricks that are needed. If we have BOMs that are many levels deep we need to run the scheduler quite a lot, and it isn't clear how many times to run it, or when we are done with running it, or what exactly it is doing. Is there any better process for achieving this? Alan.
