What model system had selected during forecast based Planning
Dear SAP gurus,
I am implementing forecast based planning for spare parts planning for my client. Following are the settings for the material master record.
1. MRP type-VV
2. Forecast model field - empty
3. Initialization indicator - X (Initialization by system)
With above settings I carried out forecast run trial for a set of materials. After the forecast run when I checked the Material master I could see three categories.
1. For some materials system had selected Constant Model D and it had populated D in Forecast model field after forecast run
2. For some materials system had selected Trend Model T and it had populated T in Forecast model field after forecast run
3. For some materials system had not populated any thing in Forecast model field after forecast run, but it had calculated forecast values ?
I have attached the screen shots for all.
I require your valuable inputs on what model system had calculated forecast values for third category i.e., How to know the model ?
