##### Comments

- The "measure" column needs to be the name of the column in the model [table].[column name] or it can be an existing measure in the model [measures].[column name].
- For details on how to employ and use this function see the granular calculation overview.

##### Different Function types

- This function is like the SQL max function; calculating the maximum of a column of data in your query or model.
- If you wish to find the maximum for the elements in a specified SET or LIST from a hierarchy, use this semantic function.
- To use a simple maximum mathematical operation on a list of numbers, use the Common library function.

#### Examples

To create a new measure that is the sum of expenses in the model, using the sample demo model:

Maximum( [data].[Expenses] )

or:

Max( [measures].[data Expenses] )

The mechanics of this function are shown below. This grid says that the maximum expense across all 'Accessory' transactions is $252.00. This was calculated by looking at every row for accessory transactions and finding the one with the highest value. This produces a different result to the Max([LIST]) function which would find the maximum value from the list of items presented instead.
