PIR Period of adjustment clarification

[scm_09]

Experts,

I would appreciate if someone can help me understand this functionality.

I have weekly forecast and the forecast will be loaded on every Monday of the week.

Days M - T - W - T - F - S - S

Fcst 10

Sale 2 - 0 - 3 - 0 - 4 - 0 - 0

We have forecast of 10 on Monday for Week 8 (as above). In that week I have sales order for 2 on Monday, 3 on Wed and 4 on Thursday. what does period of adjustment set to 3 days do to my forecast and planned orders?

Hi

Period of adjutsment maintained at plant level is used to detrmine the Key date which is proposed on MD74/MD75/MD76.

 Reorganization Interval

With the reorganization function, you can delete planned independent requirements for which there are no sales orders in the database. You can delete the planned independent requirements history. 

A key date is required to carry out reorganization which is calculated as follows: the system checks whether a reorganizing interval is maintained in Customizing for the plant that you want to reorganize. If an interval is maintained for this plant, the system uses this information to calculate the key date. If no interval is maintained for this plant, the system checks whether intervals are maintained for any other plants, and selects the largest interval to calculate the key date. You can change the key date proposed in the initial screen for reorganization. 

You can change the proposed key date when deleting the history. You can set a shorter interval for deleting histories than for deleting the requirements records. 

The reorganization of the planning data is performed at the following levels:

Adjusting requirements
In the adjusting requirements function, the system checks whether there are customer requirements for the planned independent requirements that are before the key date for the reorganization. The system checks the amount of customer requirements that can be allocated to the planned independent requirements. The planned independent requirement quantities that received no allocations are set to zero, and are included in the reorganization process. Inactive versions are deleted.

Reorganizing schedule lines
The system checks which planned independent requirements are set to zero due to reduction, consumption, or the adjusting requirements function. Requirements records, that is, the planned independent requirements schedule lines with the quantity zero, are deleted.

Deleting histories
You can delete the planning history when the accompanying requirements are deleted.

Santosh,

I guess Period of adjustment is a different concept than MD74/75/76. Thx
