Replenisment control behaviour

[ilya_terentiev]

Hello,

I try to understand replenishment control behaviour in the system:

I've made all necessary customizing settings:

- Storage type for replenishment

- movement type for replenishment and assigned it to storage type

- Activated storage type search

- Extended material master on storage type and added max. bin quantity, min. bin quantity and replenishment qty.

Everything works fine for t-code LP21- but i can't understand on thing:

1st case:

In material master i enter:

Max. qty - 74 pc

Min qty - 1 pc

Replen. qty - 50 pc

In LP21 system defined requested qty as 50 pc

2nd case:

In material master i enter:

Max. qty - 75 pc

Min qty - 1 pc

Replen. qty - 50 pc

In LP21 system defined requested qty as 100 pc

What is the logic? why requested quantity changes from 50 to 100? Doesn't have to be alsways 50 pc?

Thank you in advance - for helpful or correct answers will be points.

Hi

The replen qty is acting as a rounding value. So in simple terms;

Case 1 - actual replenishment qty = 1 full replen qty + X (<=49%). Outcome = 1 full replen qty = 50

Case 2 - actual replenishment qty = 1 full replen qty + Y (>=50%). Outcome = 2 full replen qty = 100

It is because of this logic that your max/min/replen qty's must be 'in sync, with each other, relevant to the max physical capacity of the bin and with consideration given to relen picking efficiencies.

Hope this helps

Cheers

How did you count that? I mean X (<=49%) and Y (>=50%).

I've divided replenishment qty/max qty

75/50 = 1,5

74/50 = 1.48

Is that correct?

Hi

74/50 = 1.48 broken down as 1 full replen qty (50) and <=49% of a whole replen qty (24)

75/50 = 1.50 broken down as 1 full replen qty (50) and >=50% of a whole relen qty (25)

Same answer, I was just trying to explain the logic as requested

Cheers

what is the stock quantity of the storage bin for the second material ? according to SAP WM replenishment process requested quantity must not exceed max bin quantity.

[ilya_terentiev]

Stock quantity is 0. For these cases is used the same material. As you see requested quantity exceded maximum bin quantity

Is the rounding qty for case 1 = 50ea and case 2 = 100ea?

Control qty and rounding qty will influence this process. Please share those details.

Edit: also, is this for case picking or for picking units from the cases and is it one step or two step replenishment process?

[ilya_terentiev]

Rounding qty is not maintained for any cases.

It is one step picking process.
