Question about MRP (dynamic safety stock) --> your help would be so appreciated...

Dear all

I am doing some research on the dynamic safety stock function in MRP.

From what I understood from reading various material was the following.

<conditions>

[Coverage profile]

1. The coverage profile has got the following parameters.

a) Determine range of coverage --> Period indicator M (Month)

b) Determin average requirements --> Number periods (3) --> 3 month

Type of per. lengh(3) --> standard days

No. of Days per Period --> 20

[Lot size in the material master data]

1. EX --> Lot for lot

[The planning date for the MRP run]

2012/06/27 (Year 2012, June, 27th)

The sales orders for the coming months are the following.

1. 2012/06: 100 PC

2. 2012/07: 100 PC

3. 2012/08: 100PC

4. 2012/09: 100PC

5. 2012/10: 100PC

6. 2012/11: 100PC

Under the conditions above, my understand for the "avarage daily requirements" for those month would be

calculated in the following formula.

requirements for each period/the total days specified in the coverage profile

So for the month of June, it would be:

Total days specified in the coverage profile = 3(Month) × 20 days = 60 days

requirements for June = 100 PC

average daily requirements = 100 PC / 60 days = 1.67

For July, it would be:

Total days specified in the coverage profile = 3(Month) × 20 days = 60 days

requirements for June = 100 PC

average daily requirements = 100 PC / 60 days = 1.67

However, when I actually have a look at MD04 for this material, the results are so different from what I expected...

I tried to understand this by myself, but it is now too confusing...

I would really appreciate any help for understanding how the avarage daily requirements for the dynamic safety stock...

Kind regards,

Takashi
