What is a planned independent requirement?

Independent requirements and dependent requirements are the two main types of requirements you encounter when configuring SAP planning. This is what they are:

Planned Independent Requirements (PIR)

Planned Independent Requirements are planned production or sales quantities that are based on some sort of forecast procedure (e.g. Material Forecast or S&OP procedure). These numbers are used in MRP to calculate procurement and/or production quantities for a material.

(Planned) dependent requirements

Dependent requirements is demand that is dependent on another material. E.g. components of a bill of material are often planned on the basis of the demand for the material of which it is a part.

Planned independent requirement reorganization

You can use the reorganization function to get rid of outdated and/or obsolete planned independent requirements. Furthermore you can delete histories of the requirements from the database.

In these transactions you work with a key date. Requirements before this date are impacted by the transactions. It is possible that a Reorganization Period is set for your plant:

IMG > >Production>Production planning>Planned independent requirements > Define the reorganization interval

You enter here the number of days that the system subtracts from the system date to fix the key date. This setting overrides any manual key date that you enter in the transactions!
