Lot Sizing

​

Minimum, Maximum Lot Size

with Rounding

Min Lot Size 100

Max Lot Size 200

Rounding value 12

Lot size key is

‘EX’ (Lot for Lot)

Notice requirement is 301,

it is above min of 100, but below max of 200,

The system tries to place order 204 (12 x 17) due to rounding of 12 (but falls back to respect the max lot size),

The remaining (301-200=101) is above the min but below the max, so system will still respect the Rounding of 12 and therefore suggested 108 (12 x 9)

We will now change the Lot size key to “FX” Fixed Lot Size

with a Fixed Lot Size of 75

See if we can retain the Min lot size 100

Max lot size 200

Rounding value 12

We will now change the Lot size key to “FX” Fixed Lot Size

with a Fixed Lot Size of 75

Enter FX and 75

Press Enter

This is not due to IMG but standard SAP delivery, not all combinations of Lot size parameters are allowed !!

Lot size key “FX”

Fixed Lot Size 75

Max Stock level 500

We now change the PIR to 501 to see if Max stock of level of 500 is really a statistical entry !!

Change PIR from 301 to 501

Changed PIR from 301 to 501, now run MRP

Changed PIR from 301 to 501, now run MRP

75 x 7 = 525, as this

75 x 7 = 525, as this exceeed the max stock level of 500 (the max stock level), it was not considered by MRP run !!
