Inventory Question

ManosA

I have the following problem.
I can't figure out what kind of information the field 'Lot Size' in the
Item card holds. Is it the number of "things" the production has produced after one full cycle of working? Is it the minimum quantity that the production
gives no matter what? And then how this number is relayted to the reordering procedure and numbers?
I can't seem to understand the Lot name and the way it is used in this field.

Any help would be highly appriciated.

Dear Manosa,
you are in the right place to ask. The lot size function in navision if you set your production qty per batch. so for example 1 batch = 1 lot size.
I lot size = 10 pcs or 20 pcs or more, so it will relates to your production order schedule and of course your material planning, so the ot size is purposed in the production order replenishment system.
As about the lot name, you can set it in the item tracking to be lot numbering.
If you set your manufacturing policy to be make-to-stock, you can use reordering policy fixed reorder quantity or maximum inventory in your planning system, it will relate to lot size that you set in the item card of your product item.

So this practically has to do with the producting setup rather than Item card or inventory?

johnson_alonso

yes, you are correct if you mean production set up is measurement in qty to produce. YOu must know that production setup defenition is many, from planning parameter set up, workshift set up, etc.
But it's not true, if you skip the other parameters in the item card. Lot size is only one of production set up.
Lot size will be related to setup time when you calculate the standard time.Don't forget to set lot size in your routing, because it can't be seen the lot size you have set up in the prod. order routing and allocated capacity if you skip to fill lot size in the routing although you fill lot size in the item card.
you can find lot size in your stockkeeping unit card, if you create stockkeeping unit from your product's item card.
As an example, in the garment production system, they cut the fabrics and bundle it 10 pcs/bundle, so it will be said 1 lot size = 10 pcs. then
The capacity cost calculation = setup time / lot size x unit cost + run time x unit cost

Thnax for the answer man. At least now it makes some sense :idea:
Currently I'm trying to study for Inventory and WMS, but I keep finding bits of information about either finance and production, which is still a bit confussing, since I'm new in Navision.
Thanx again.

it's a good info. You must also write the calculations in inventory and also edit some words in the no. 4 of 1st paragraph of this site : http://navitips.blogspot.com/2006/03/un ... y-and.html , you wrote FEFO, it must FIFO, but is it a new method..(first expired first out-FEFO) like in the food and pharmaceutical industry..?

Yeah, it's first-expired-first-out, very important in food and agro.

You don't understand what I mean. DO YOU SEE FEFO IN NAVISION..? you make people wasting time just to browse your blog.
Your short reply makes me want to punch the stone and fight...
