Changing the Period Unit in the Planning Table 
You can change the period unit of either the entire planning horizon or a preselected part of it on the following conditions:
- The planning method of your information structure is level-by-level (standard SOP or flexible planning).
- No storage periodicity has been defined for the information structure in Customizing (in Set parameters for info structures and key figures).
You can plan in days, weeks, months, or posting periods. You can also disaggregate part of the planning horizon on a time basis: the system then breaks it down into smaller period units.

Most changes of period unit are possible. However, the system does not allow you to switch between month and posting period.
- Changing the period unit of the entire planning horizon
To change the period unit of the entire planning period, choose Edit → Period split → Total and the desired option.
- Changing the period unit of part of the planning horizon
To change the period unit of part of the planning horizon, select this block in the planning table and then choose Edit → Period split → Selective and the desired option.
- Disaggregating part of the planning horizon on a time basis
To disaggregate part of the planning horizon on a time basis (for example, from week to day), select this block in the planning table and then choose Edit → Period split → Selective → Time-based disaggregation (disagg.).
