Planning Calendar (SAP Library - Material Requirements Planning (PP-MRP))

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 Period Lot-Sizing Procedures).

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.
