Hi,

Planning calendar is use at material level and you can assign this in MRP2 view along with lot size procedure (period lot size according to planning calander PK).

By doing this procurement proposals will be created according to the periods defined in the planning calendar. for example period start date in Friday in the planning calendar and periods are weekly then during MRP for all requirements which falls under this weeks will cumulated and MRP will create single procurement proposal (planned order) on Friday for this total weeks requirements.

Create one Planning calendar in MD25 specifying each period as per your requirement.

Maintain Lot size as PK (MRP 1 view) and Planning calendar(MRP 2 view) in material master.

After MRP system will group all the requirements in each period and creates PR according to the planning calender.

Hope clears to you.

Hi,

Pls. find the details about Planning Calendar as follows :

Planning Calendar

Definition

Planning calendars define flexible period lengths for material requirements planning at plant level.

Use

· Using the planning calendar, you can define flexible periods for a period lot-sizing procedure in master production scheduling and in MRP. The system groups together the purchase order proposals, which fall within the period defined in the planning calendar, to form a lot. You allocate this special lot-sizing procedure to the material in the material master together with the planning calendar (see Periodic Lot-Sizing Procedure).

· You can also use the periods in the planning calendar for the period totals display in the stock/requirements list. If a planning calendar is valid for a particular material or if a planning calendar is entered at plant level in Customizing, the receipts and issues in the period totals display can also be grouped together according to the periods of the planning calendar( see Display of Period Totals).

· Finally, you can also use it to define flexible splitting periods for demand management. The total planned independent requirements quantity for a certain period (for example, for one year) is then divided up according to the period defaults in the planning calendar.

Creating Planning Calendars with Calculation Rule

1. In the menu, choose MRP ® Master Data ® Planning Calendar ® Create Periods.

The screen used for maintaining the planning calendar now appears.

4. Enter the following data in the maintenance screen:

¡ The short description of the planning calendar

¡ The minimum period

The minimum period is used as a time limit for maintenance of a calendar that is no longer valid. You use the minimum period to define the period necessary for reprocessing the calendar. If the time limit is exceeded, the system displays the calendar for processing (see Changing the Planning Calendar), even when the Valid to date has not been reached yet. You should therefore define the minimum period so that the system displays the planning calendar for processing on time in the future.

¡ Specify how the system should proceed if the period start happens to fall on a day that is not defined as a workday in the factory calendar.

5. Choose (Continue).

6. The system displays the Select calculation rule dialog box. The calculation rule determines the calculation of the periods for the planning calendar.

Choose the calculation rule you require:

¡ Weeks (weekdays)

Example: period start on Monday and Wednesday every week

¡ months (weekdays)

Example: period start on every second Wednesday of the month

¡ Months (workdays)

Example: period start on every fifth workday of the month

You can specify the workday/workdays of the planning calendar according to the workdays defined in the factory calendar.

¡ Years (workdays)

Example: period start on every fifth workday of the year

You can specify the workday/workdays of the planning calendar according to the workdays defined in the factory calendar.

¡ Workdays

Example: period start on every fifth workday from a particular start date

You can specify the workday/workdays of the planning calendar according to the workdays defined in the factory calendar.

¡ Weekdays

Example: period start on every second Wednesday from a particular start date

7. Choose (Continue).

8. Enter the necessary data in the Calculation rule for period specification screen area.

9. Choose Calculate periods.

The system displays the New dates dialog box.

The system displays a start date in the Valid from field. You can change the date here, if necessary.

In the Valid to field, the time period that results from the minimum period is displayed. Here, you enter the date up until which the system is to calculate the periods.

10. Choose (Continue).

The system then displays the calculated periods.

The number of the displayed periods is used in the stock/requirements list for the period totals display, if the display is set according to a planning calendar.
