Business Requirement: The Planned Independent requirement should not be considered in a short-term horizon. Let’s say the planner enters PIR’s for the current month and the following month. The sales orders arrive which consumes the PIR’s. This means the remaining Planned Independent Requirements should not be considered for production.

 

Solution: You may use the function called ‘Adjustment Period’ in the MRP Group. You must define the period of adjustment for PIR’s as 22 days as an example. The adjustment period is calculated in workdays (according to the Factory calendar) therefore 22 workdays would mean an adjustment period of 1 calendar month. Also, the indicator for Adjustment of Planned Independent Requirements must be assigned. This indicator is used to identify if the adjustment is performed backwards or forwards. You can also determine if the adjustment of PIR’s is valid for all planning strategies or only for PIR’s that are planned with a strategy which includes the consumption of customer and independent requirements.


Now, lets create Planned Independent Requirements for a material. Currently the MRP group with adjustment period is not assigned to the material. You can see that PIR’s are displayed as a demand in MD04.


 

Now, assign the MRP group ‘0001’ with adjustment period to the material and then run MD04 again.


You can see the PIR’s are displayed in MD04 however not considered for planning. The field ‘Available Quantity’ for each PIR is blank.

Conclusion: Adjustment period can be used to ignore Planned Independent Requirements from planning run.
