PLANNED REPLENISHMENT IN EWM
Replenishment is defined as the movement of goods from the warehouse to the shipment locations. In SAP EWM, you can use predefined techniques for replenishment of storage bins. There are different replenishment control fields defined at the storage type level or storage bin level.
Planned Replenishment:
In planned replenishment the system calculates the replenishment in accordance with the defined minimum quantity and maximum quantity. Replenishment control is triggered when the stock is less than the minimum quantity. The system rounds down the replenishment quantity, in other words, the quantity of the warehouse task or the warehouse request, to a multiple of the minimum replenishment quantity.
Replenishment at storage type level or storage bin level
Define two storage types (NESB & NEST) and select replenishment level at storage bin level for fixed bins and storage type level respectively
Create bin (fixed bin) for the storage type NESB T.Code : /n/scwm/ls01
Define one storage type (NEST) and select replenishment at storage type level
select replenishment at storage type level
Create one storage bin for the storage type NEST (NEST-01-01-07) T.Code : /n/scwm/ls01
Now go to spro and activate replenishment strategies in storage types (NESB and NEST)
warehouse process type 3010 is used for replenishment
Determine warehouse process type
Go to T.Code: /N/SCWM/FBINASN assign fixed bins for replenishment at storage bin level
Go to T.Code: /N/SCWM/BINMAT and maintain the the fixed bin
NESB-FIXEDBIN200 is maintained for storage bin and execute it
here maintain minimum and maximum quantity of products for storage bins
Now go to T.Code: /n/scwm/mat1 create and add storage type NESB ,,manintain minimum replenisment quantity
now go to spro and maintain picking strategies for replenishment
Define stock removal control indicator
Go to T.Code : /n/scwm/repl and start planned replenishment
enter details like warehouse number, storage type and product execute it
replenishment run started and warehouse task 103800 is created
now go to warehouse monitor and confirm the warehouse task 103800
fixed bin NESB-FIXEDBIN200 is replenished with 28 products
Replenishment at storage type (NEST)
Go to T.Code: /n/scwm/mat1 add storage type NEST in the storage type view enter maximum bins minimum replenishment quantity , minimum quantities and maximum quantities
now lets execute replenishment at storage type level
maintain minimum quantity maximum quantity and minimum replenishment quantity
Go to T.Code : /n/scwm/repl and start planned replenishment
go to warehouse monitor and confirm the warehouse tasks
confirm the warehouse tasks 103801 and 103802
storage bin NEST-01-01-07 is replenished with 30 quantities
conclusion :
Replenishment is an internal process and is used to fill up a picking area in accordance with the demand for products.normally warehouses have primary picking zones and buffer zones to manage their inventory. These primary zones are maintained nearby to door areas to use as picking area and maintain with predefined maximum, minimum stock quantity levels. whenever any product stock level falls below minimum stock level, a replenishment WT executes to fill stock up to maximum level.
There are two levels to control replenishment process, one is at storage type level and other one is storage bin level. It means required material quantity can either be determined for the storage type as a whole or, in the case of a fixed bin scenario, for each individual fixed bin in the primary area.
Great document. Thank you.
