Replenisment control behaviour

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

      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

    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?

    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.
