Changing all-name in dimension

When working with cubes and dimensions and you have a dimension with time for example, you have the value "All" default added. "All"means that you select all occurrences in the time dimension, selecting the measures over all time.

When you create reports using cubes, this all-value is default added to the report as well. So when you create a parameter, "All" is included in the dropdownbox:

To support your users, "all" is not the best discription that can be added. A better option would be "all time", or "last 5 year" (depending on the horizon of your dimension).

To change this default behavour, go to your cubedesgin and go to the properties of your dimension. Then change the field AttributeAllMemberName to the disired name:

Leaving it blank will default add "all". Changing the property will add your given name as all-value.
