Procedure documentation Automatically Generating PPMs for Demand Planning Locate the document in its SAP Library structure

Use

Use this procedure to generate PPMs for use in Demand Planning from existing SNP or PP/DS PPMs. The procedure explodes multi-level PPMs to produce a single level DP-PPM.

This graphic is explained in the accompanying text

The system first completely explodes the multi-level PPM and calculates the quantities of the input products. Any products that are not relevant for DP, that is the SDP Relevance indicator on the Attribute tab page of the product master has been set to 1 or 2, are not included in the DP PPM. In the example in the graphic above this would mean that the following products and quantities would be included (for simplicity just "A" products):

Product

Quantity

A

2

A2

2

A11

12

A12

6

A111

12

A112

12

Note

After you have created a DP PPM, there are no hierarchical relations between components. In the example above if you change the quantity of component A11 in the DP PPM, the quantities of A111 and A112 will remain unchanged.

 

Prerequisites

A PPM exists for the top-level product.

You have create a master planing object structure for use with bills of material as described in Forecasting with Bills of Material.

Procedure

  1. Create the master data for Demand Planning, the characteristic value combinations, based on the master planning object structure you created in step 4 of the process described in Forecasting with Bills of Material.
  2. The field for the characteristic PPM is grayed out. The PPM information is not generated in this step.

  3. Return to the initial screen for master data maintenance. A Generate DP PPMs... button is now available. Choose this button. A selection screen appears.
  4. Enter the master planning object structure and the model to which the new PPM is to be assigned. If the PPM is to be location-specific, choose the Location-dependent indicator. You can limit the selected PPMs to those valid for certain characteristic value by choosing the Selection condition button and making the necessary entries.
  5. Choose This graphic is explained in the accompanying text. A table appears with all PPMs that exist for the selection.

  6. This table consists of the product name, the location, a suggestion for the plan name and a traffic light icon, which signifies the following:

Action to be taken

This graphic is explained in the accompanying text

No DP PPM exists for this product or location product

Generate a DP PPM by choosing This graphic is explained in the accompanying text.

This graphic is explained in the accompanying text

A PPM exists for this product or location product, however it has not been assigned to the current model

Assign the DP PPM to the model by choosing This graphic is explained in the accompanying text.

This graphic is explained in the accompanying text

A DP PPM exists for this product and it has been assigned to the current model.

The PPM exists. Now you must assign it to master planning object structure as described in step 8 of Forecasting with Bills of Material.

 

Generating a DP PPM

  1. Select a product or location product from the table and choose This graphic is explained in the accompanying text. A new screen appears.
  2. On the top half of the screen enter data to select the PPM, such as lot size, evaluation date and planing version. You must also stipulate whether you want to search for SNP PPMs or PP/DS PPMs.

On the lower half of the screen enter details for the new DP PMM, such as the validity dates, the lot size interval and quantity to which the PPM refers.

Choose Product/Location/Plan to change the name of the new plan.

Choose This graphic is explained in the accompanying text.

If the PPM is generated successfully, a corresponding message appears and the traffic light changes to This graphic is explained in the accompanying text. Otherwise a log appears informing you of the problems the system encountered.

Assigning the PPM to a Model

  1. Select a product or location product that has status This graphic is explained in the accompanying text. Choose This graphic is explained in the accompanying text.
  2. If necessary enter the model to which you want to assign the DP PPM. Choose This graphic is explained in the accompanying text

The DP PPM can now be used for forecasting. To assign the PPM to the master planning object structure proceed as in step 8 of Forecasting with Bills of Material.
