How to maintained forecasting master data for Automatic reorder point Planning

Hi All,

My client currently having manual ROP in place and wants to implement Auto reorder point planning, currently they don’t use forecasting so i have to suggest which is better for my client.

I have tested couple of different scenarios and changed forecasting fields and getting new result which I don’t understand. What fields should I maintained to work auto ROP Process works? Below is the master data I set up. I am using a testing materials which has last 12 months or more consumption for material type HIBE & ERSA.

MRP 1:

MRP Type: VM

Reorder : Blank(empty)

Lot size- EX or TB

MRP 2:

Service level - 90%

Safety stock: Blank(empty)


Forecasting model: J

Hist. periods- 12

Forecast periods- 12

Periods per season- blank

Initialization periods- blank

Initialization- X

Tracking limit- 4

Optimization level : F

Parameter optimization checked

Reset automatically checked

Selection procedure- 2 ( I have tried selection procedure 1 and 2 and results are different, I have saw in other treads that selection procedure 2 is better but take longer time) what is the difference between these two selection procedures ?

Execute forecast:

Aut. Model selection

Chose : Forecast model sel. Using procedure 2 ( I also tried the one system choose it self - which way is better ?)

I want to know which fields should I maintained in forecasting master data (standard) to work auto ROP process and If i select forecast model "J" (automatic) and selection procedure 2, should i execute forecast which system is suggesting(system selecting it self? and how I can calculate the results.(basic value, MAD, reorder point and error total)

I have saw other treads but it didn't cleared my question regarding this process to work.

I really appreciate if someone help me out on this process .

Many thanks in advance.
