1. Go to analysis tab and create a parameter. (below for example)
2. Click on set from field, a set of data sources used are shown, select the source and then select the measure. the follow same procedure and select multiple measures.
3. This way multiple measures can be used for the same parameter. But parameter is a one input value so only one measure can be selected at a time as a dynamic value. (multiple measures in same parameter is not preferred)
