# Base Quantity

Hi SAP Seniors,

What is the role of Base Quantity being played in BOM & Routing .? Can anybody explain me with an example.

How it is different from Costing Lot Size and CO Quantity ?

Thanks & Regards

Hi,

Based Qty- if you want to produce one item, the BOM is created based on its Base Qty.

Lot size, it is for costing. if you maintained lot size the system will take costing for this info, otherewise it will pick from base qty.

Thanks.

Hi,

Base Quantity is a quantity which required to produce the Finished product or semi finished product.

Example:-

Lets Assume you are manufacturing one Finished Product, for this you required Raw Materials.

Go to the T.Code: CS01

Specify the Material: Finished Product

Plant : XXXX

Item ICt Material Quantity

0010 L Raw Material 10

For the above example, to manufacture of 1 Finished goods, you required 10 quantity of the Raw materials.

Where as Costing Lot size will be used in the Product cost estimate in CK11N.

Thanks & Regards

Hi,

Base quantity is your produced qty out of a production order.

In simple words, if you produce 60 Kgs of material by giving input of 100 kgs.

Here, your base qty would be 60 kgs and in BOM components you will give the raw material/semi finished goods as 100 kgs. and remaining 40 kgs you can consider as co-product by giving -ve sign while entering qty for it.

Other case, if you are producing 100 kgs of A finished good, with components of 20 kgs B, 30 kgs C, and 50 Kgs D materials. Here, base qty is 100. Ultimately, base qty should be equal to the qty of your components in the BOM.

Costing lot size is used for costing purpose. Usually, we will give the costing lot size in material master, based on the lot size it will give you the cost in analysis. But it will not change the individual unit price.

The base qty is the qty in the BOM in terms of which all other qties are entered.

The lot size is the optimum manufacturing qty - it might be a bad idea to manufacture one by one, rather start the machines up once and do a lot size of a thousand. This is especially useful in the case where there is a large setup cost involved for a production run.

The costing lot size is similar to that. The costing run will calculate the costs as per the costing lot size (CLS). SO if the CLS is 10 000, the costing run will assume that you want to manufacture 10 000 at a time, and do the calculation that way. But you can also use that to get a more accurate calculation - it effectively increases the number of decimal places, or more accurate the significant digits, for your answer.

Hi

If you want you can reverse the confirmation and make the base qty to 60 also relevant BOM components qty accordingly. Again you can confirm the same with 60 qty.
