I want to make a demo whose period level is the week (that is, more detailed than the month), how would it be done?
Please get the week level detail column for Time Period under Visualization Pane. Then configure the Data series Manager(Mode Tab>Data series>Data series Manager) with the number of weeks in Period tab and Name of the weeks in Period Label Tab.
Yes, you will have to prepare 2 different models which gives the detail at Weekly and Monthly level.
This can be done by using ValQ’s Export as Data source option with which you can easily create another model after performing some data transformation in Power BI Query editor.
