Hi All

Pls confirm is it possible to bifurcate the child component requirements (PR;s or Pld Orders) on Days or week basis where the parent requirement or PIR's are defined on Monthly Basis . The vice versa is achieveable but pls confirm whether this scenario ncan be done or not . The scenario in explained is as follows

Material Parent A Lot Size - MB and PIR defined Period is also M (Month)

After MRP the Planned order is generated on 1st of the Month

Lets Say Child Component B has lot size WB or TB

Can I get the requirements on weekly or daily basis (Taking the prpotional value of A over the defined period)

Also confirm me where can I define the LOT size parameters ie If I want to generate PR thrice a week or fortnightly , how to define the lot size calculations

Best Regards

Manoj

Hi

MRP 1 View there is field called planning cycle. If you define your own planning cyle and include here then also you can acheive the required results

Hi

Create the Production version for the particular material for which you are going to use the planning table.

create production version in c223 or in mmo2/ mrp 4 view

HI,

yes we can do as you required. actually we do same process as you expect.

the scenario that you gave :

Material Parent A Lot Size - MB and PIR defined Period is also M (Month)

After MRP the Planned order is generated on 1st of the Month

Lets Say Child Component B has lot size WB or TB

Can I get the requirements on weekly or daily basis (Taking the prpotional value of A over the defined period)

Solution i suggest is :

1... RUN THE MPS (MD42) FOR THE ( final ) PARENT MATERIAL.

- SO SYSTEM CREATE THE PLANNED ORDER FOR THE FINAL PRODUCT AND CREATE THE DEPENDED REQMT FOR THE NEXT LEVEL COMPONENT /ASSEM.

2.... IN MDO4 YOU CAN SEE THE ONE PLANNED ORDER CREATED FOR THE MONTHLY REQMT,

3.... GO TO THE PLANNING TABLE (MF50) . AND GIVE THE FINAL MATERIAL / PRODUCT GROUP IN WHICH YOUR FINAL MATERIAL IS A MEMBER .

- HERE GIVE THE PERIOD AS DAY IN THE FRONT SCREEN. AND EXECUTE.

- SO THE MONTHLY REQMT WILL BE COME IN THE NEXT SCREEN.

- GO TO MENU PATH - VIEW -PERIOD - MONTH - SO SYSTEM SHOW THE MONTHLY REQMT FOR THE PARENT MATERIAL

- NOW DELETE THIS MONTHLY REQMT AND SPLIT INTO THE DAILY / WEEKLY REMNT AS YOU REQUIRED.

4.... IN MD04 , NOW YOU CAN SEE THE PLANNED ORDER GET CHANGED AS PER THE DAY REQMT.

5..... IF YOU CHECK FOR THE COMPONENTS, YOU CAN SEE THE DEP REQMT WILL BE CREATED AS PER DAY/ WEEKLY BASICS.

6.... NOW RUN THE MRP FOR THE COMPONENTS

7.... SO SYTEM WILL CREATE THE PLANNED ORDER / PR CORRESPODNING TO THE DAY/WEEKLY WISE DEPE REQMT.

Lets Say Child Component B has lot size WB or TB

MAINTAIN THIS LOT SIZE AS YOU REQUIRED.
