Question: Looking at the time dimension, it seems only one time dimension can be created per application. If you add time profiles, it still uses the same time dimension of the application.

Answer

• It is correct that each application has a time single time dimension.
• This can be customized to include additional periods or include weeks.
• This need to be defined prior to building the application.
• Time profiles are created within the application and allow you to alter the descriptions of the time members by cube.
  • For example, if you needed different fiscal years in a single application, different time profiles could be created and assigned to different cubes.
• The “Input Frequency” Scenario setting controls how data is stored for that scenario.
  • Utilizing this setting allows a client to combine monthly, weekly, yearly and quarterly reporting processes in the same application.
  • The data is stored against the relevant time member based on this setting on the scenario
    • Example:  In a monthly scenario, data will be stored against M1, M2 etc.
• Thus, there is not a need to have multiple applications when some processes require monthly data and others require weekly data.
