Dear colleagues,

i have a requrirement that sound very strange at the first time without explanation...

I'm looking for 2 minimum lot sizes for one material in one plant.

I will try to exaplain:

there is a material that always should be manufactured with a production order of 1000 pieces (fix lot size) It's restricted by the machine we manufacture this material. So far no probem but there is a second restriction.

MRP-run should always create minimum quantity of 3000 pieces.

So in best case MRP never creates one planned order lower or higher than 1000 pieces but always create minumum 3000 pieces in total (3x1000 pieces).

I have no relevant idea to meet this requirement ....

I have tried lot size FS, takt time and so on

anybody any idea ? any solution by rounding values ?

thanks in advance for your feedback.

Hi Manuel,

I would recommend to use Rounding profile for this issue.

As per your std validated batch size or Lot size prepare Rounding Profile in such a way that system only propose Lot size as per your different lot sizes.

For this first you have to define your minimum and maximum lot size limit in Material master MRP - 1 view.

Then Create Rounding Profile using T. Code OWD1


Second option is you have to create different Production versions for different lot sizes.So that during MRP/MPS run system finds the neares production version to that order qty.

In Production order type T.Code COR4 you can set manual selcetion of Production version.But it only works during Manual Process order creation.

Please refer below SCN link

Hi G.V.Shivakkumar,

many thanks to your answer.

I tried to create e corresponding rounding profile but i think i have any error in reasoning..

would you be so kind and give me an example how to set the rounding profile for my example described ?

I'm not sure if my requirement can met with a rounding profile... or do i have to use fix lot size ?

Many thanks in advance for help !

If you have a fixed lot size of 1000 then why do you expect a single planned order for 3000?

this is not logical as you can only produce 1000, and need 2 further orders for the other 2000.

See the documentation in on fixed lot size which clearly explains "If the quantity being rounded is greater than the fixed lot size, the system generates multiple orders"

you are correct Jürgen.

my target is to get every planned order with 1000 pieces, but always minimum 3000 pieces in total.

With rounding values i can go to the 3000 but i get 1 planned order with 3000 and i want to achieve 3 orders a 1000.

If i have a demand of 4000, i want to get 6000 in sum but 6 orders a 1000...

any idea ?

Had you tried?


sure, i tried wirh minimum and maximum lot size in combination with rounding values....

maybe i have any mistake in my logic, i tried some combinations but not get my target.

any concrete proposal regarding my example ?


we were talking about fixed lot size and rounding, not about minimum and maximum lot size.

Just show your setup of the rounding profile and the people here might immediately be able to help further.


we are talking about both, after i dind't get a solution with min and max lot sizes, i wondered if fix lot size would help...

i will show my setup when i'm back in the office next week, hope this will clear.

here only a short overview, what i have tried because I'm not in office...

lot size should alwaysa be 1000

and the total planned qty always min. 3000

any idea ?

What is the benefit of using minimum and maximum lot size if their quantity is equal?

Isn't this just fixed lot size then?

Based on the profile shown (if it is the one used) I would expect 6 orders for 1000. What do you actually get if you have a demand of 4000?

You should not hide the most essential information which is needed to verify that the second screenshot really belongs to the first screenshot.


the idea of min and max lot size with 1000 was to get only planned orders with a lot size of 1000. That was just an idea.

Fixed lot sizes ignores any rounding profiles.

Acutally i get 4 orders a 1000 pc with a demand of 4000.
