3136627 - Multiple Planned Independent Requirements existing for one period

There are multiple Planned Independent Requirements (PIRs) of a material exist for one period in your system. After you update the PIRs using app Maintain PIRs, these multiple entries still exist and don't merge.

This situation arises if there are schedule lines that do not fall on the first workday of the period.

The dates used in demand management are individual dates. Monthly requirements, weekly requirements and requirements for the planning calendar or accounting periods are created for the first workday of the period. You can check the detailed requirement dates in the app Stock/Requirements List. As a result, if the database already contains a schedule line with a date that is different from the first workday of the period, the system will treat them as two dependent requirements and will not combine them together.

A weekly/monthly schedule line that is not on the first workday of the month may be created as a result of the following processes:

• The schedule line was created when the first day of the period was not a workday. After that, the factory calendar has been changed.
• The planned independent requirements were transferred to demand management with a certain date not the first day of the period from other systems using APIs or direct input.

To avoid subsequent problems, we recommend that you do not create planned independent requirements with dates that are different from the first workday of the period.

If there are already requirements that do not fall on the first workday and you want to adjust them, we recommend that you delete the existing schedule lines and then create the requirement again. In this way, you will have one schedule line for one period that falls on the first workday of the period.
