Questions about sub assemblies.

We currently don't have sub assemblies but I am going to be helping a sister company that uses them allot. I have a few questions.

1) They don't list the sub assemblies as sub assemblies, they list them as Material lines. What effect does this have? I do understand the reasons as it relates to scheduling.
[Gil Amilbangsa] The check box "Pull as Assembly" determines whether a component item is intended to be made within the same Job Order as the parent-item. When a job is created, all materials ticked "Pull as Assembly" will be in the sub-assemblies section of the Job BOM.

If this box is not checked, then the part is intended to be pulled from inventory (as a part). If the part is a non-stock item and this box is unticked or if the part is not available in stock, you will need to create a separate Job Order to fulfill the requirements of the parent-item Job Order.


It makes no difference with scheduling, per se, which ever way you go. At the end of the day, you need the component when it's called for by the parent Job Order. Job Scheduling/MRP will come up with the same schedule for the component part. However, bear in mind that if a component is pulled in as material (i.e. not "Pull as Assembly") you will need to make the component on a separate Job Order sooner or later depending on your stocking levels of the item. If you do not intend to stock this component, it may be better to always pull that part as an assembly and make it on the same Job Order as the parent-item. This will save you the chore of creating too many Job Orders when one is enough.


The larger impact, from my point of view, is in the "costing" aspect. When an component is pulled in as an assembly into a Job, then all the set-up costs in the BOM will be loaded onto that sub-assembly. If you're making just one and the set-up time is an hour, then you get hit by that full hour. Pulling from stock will give you markedly different "costs" for the component depending on your costing method, costing lot size used, the way the BOM is set-up, and the actual replenishment lot sizes used. If it makes sense to make the component in batches and keep as a stocked item, it may be better to always pull that component as material from inventory.

2) What happens if they do move the assembly from the material line to an assembly line in the part master, then at production time, when a job is created, they realize that they have one or all of these sub assemblies sitting a a shelf somewhere? I would assume that when the job is created, the Parent Production Qty is propagated to the sub assemblies. So, what does this then do to costing and production requirements? Since one is in stock and the others are manufactured, who is this handled?
[Gil Amilbangsa] When the Job Order is created, you have the option of pulling sub-assemblies from stock if you have them available. You can even have a mix of qty make direct and pull from stock. Component pulled from stock will be at inventory cost. Components made direct will be costed at the actual manufacturing cost incurred on that job level.

One irritating aspect of pulling a sub-assembly from stock is that you are not able to backflush. You need to issue the sub-assembly in a separate transaction. Which is not a big deal if the sub-assy is slow moving, costs a lot fo money, or subject to overruns. If you find yourself constantly issuing a sub-assy from stock, it may be worth considering whether that part should be a stocked item.

3) Are they better off leaving everything as a material line?
[Gil Amilbangsa] Not necessarily for the reasons stated above.

Thanks for the help,
Jeremy

Jeremy,

We use Sub Assemblies every day. You can do a pull against the ones that
are in stock. However, if you plan scrap quantities for attrition they will
disappear. You will have to go in and put in an over run quantity to
correct this.

The responsibility is the Materials Manager or the Production Planner.

Wayne
