What is a Planning Procedure 

They are strategies that determines the actions to be taken on the occurrence of certain events.
Example of events: when we change an order quantity, when we create a planned order, or create a forecast, or create a dependent requirement/ and so on.

The system immediately executes automatic planning for products which has a relevant planning procedure. 

This setting is necessary when you want to planning with PP/DS (Production Planning and Detailed Schedule).

Settings 

To use planning procedures you have to set the indicator "Change planning Active" in the Planning version (/SAPAPO/MVM). With this indicator, the SAP APO system reacts to each planning-relevant event for a product, according to the PP Planning Procedure set in the location product master. For performance reasons, you should only set this indicator if you really want to work with PP/DS in the planning version.


Besides that, the planning procedure is configured inside the Product Master (/SAPAPO/MAT1), in "PP/DS" tab, and it is mandatory for Production Planning and Detailed Scheduled (PP/DS).

In this setting you can choice between all planning procedures that there are in Customizing.

 

To see the settings for each Planing Procedure, you may access customizing:
Tcode /SPRO > Button “SAP Reference IMG” > APO > Supply Chain Planning > PPDS > Maintain Planning Procedures

Click on the clock (IMG-Activity) to enter in the change view. here will be shown all planning procedures created on the system.

SAP delivers standard Planning Procedures that it recommends you to use in certain scenarios, however, the customer can also define his own planning procedures. 

Standard Planning Procedures

Lets take a look in the behavior of the Standard Planning Procedures. 

For this, we will use the information below:

We want to plan a notebook, and this notebook is composed by: memory, HD, motherboard and so on. Hence, when we create a planned order for the notebook, the system automatically create Dependent Demands at the components.

We will see what will happen when we assign the following Planning Procedures to the components.

 

1 – Manual planning with check

This Planning procedure basically verify if the product/component is available.

One of the events and actions is:
Event "Create or Change Dependent/Stock Transfer Requirement in PP/DS"
Action "Cover Dependent/Stock Transfer Requirements Immediately With Existing Receipts" 

For example:
When we create a planned order for the notebook, the system search a receipt to cover the demand for the components if it does not have stock available.
And if the search does not find any result (this means, if there are not receipts for the dependent demand in the memory) then the system does not allow the creation of the planned order. And in this case is showed a error message like this:

 

2 – Manual planning without check

With this planning procedure the component is always considered available, independent of the receipts. This means that if there is a shortage for the component, the shortage will be retained.
In this planning procedure there is no action associated to the event “Create or Change Dependent/Stock Transfer Requirement in PP/DS”.

For example:
Following the previous example, when we create a Planned Order for the notebook, the system will just allow the creation of the Dependent Demand for the component, and will not create any receipt to cover the demand. Possibly there will be shortages.


3 – Cover dependent requirements immediately

With this planning procedure assigned to the component, the component is automatically planned when there is a modification.

One of the events and actions is:
Event "Create or Change Dependent/Stock Transfer Requirement in PP/DS"
Action "Cover Dependent/Stock Transfer Requirements Immediately"

For Example:
When we create a Planned Order for the notebook, the system will verify if there is a shortage in the component, and if yes, it will create new receipt elements for this component immediately after save the planned order.

 

4 – Planning in planning run

With this planning procedure assigned to the components, the system creates a planning file entry for the product. This means that the product will not be planned automatically, otherwise will be created a planning file entry on that product to indicate that there were changes which can influence in the planning.

So, one of the events and actions is:
Event "Create or Change Dependent/Stock Transfer Requirement in PP/DS"
Action "Create Planning File Entry”
Reuse Mode "Use Suitable Receipt Elements"

The Reuse mode is the value that will be assigned to the Planning File Entry of the product, this means that the planning file entry has a reuse mode.

To plan a product which there is a planning file entry, we can execute net change planning in the Production Planning Run (/SAPAPO/CDPSB0), using an MRP heuristic that calls the product heuristic to plan the product.
Is important to know that for to do this, we have to set the field “plan file entries” when run the Product Planning Run.

For Example:

When we create a Planned Order for the notebook, the system will create the Dependent Demand on the component and this demand will not be cover automatically. The system will set a Planning File Entry on the component.

This Planning File Entry is useful because determines how the product will be planned in the Product Planning Run, and can be saw in Tcode /SAPAPO/RRP_NETCH, as showed below:

The possibly planning file entries are:
