Hello,
I have the following situation occurring and I am not sure if this is normal for the system.
1. I have a project for which I have an item requirement. The item is manufactured and in its bom is a part which itself is manufactured. There is also a part that is purchased.
2. The project mentioned in step 1 has some financial dimensions.
3. I have no other orders or on hand stock
4. I run MRP and as expected it suggests 2 production orders and 1 purchase order
5. The parent production order has the same financial dimensions as item in the item requirements.
6. The production order for the lower level item though and the purchase order for the purchased item both do not have any dimensions from the project.
I have not been able yet to ascertain if the fact that start from a project is relevant to the scenario or if the same result would have happened if I had a top level Production order created manually and then demand for the lower level assembly (production order) and purchase order - created by running MRP.
I can see why the system might behave like this if you consider that in MRP the system will not be concerned with individual orders and tries to create the optimal purchase and production orders, respecting lead times, time fences, vendor discounts etc, so maybe it is not possible to then create a one for for purchase/production order for each demand and since the supply by MRP consolidates the demand - then it is not possible to retain the financial dimensions lower down in purchase and production orders. e.g. if a have a dimension called region and a Prod order for the north region to make 2 bikes and a prod order for the south region to make 3 bikes. I now need a prod order or order for 10 wheels - so MRP can make a prod order for 10 wheels but then which region will it get - it cannot have both since Prod Orders do not have lines like a purchase order does. So this might be the reason for this behaviour but then how do we use the system. At the end there is one labour recovery account used for the route consumption (in the cost category) for all Prod orders - you cannot enter one account for production orders that are 1st level and those for lower levels of the BOM. Right now we are finding that before we firm the production orders generated by MRP and before confirming the Purchase orders from MRP - we need to manually enter some financial dimensions on them slowing the process. Has anyone experienced the same scenario and if so what did you do?
