Within the MUX when reviewing the available columns to add to a grid, you can perform a search to filter attributes. If you search for a word that is included in the Object, all attributes associated to that Object are included.
An example of this behavior:
1. Log into the MUX and go to the Project module.
2. In the Grid view, click the "Columns" tab on the right side to see the list
3. In the Search bar enter "Period"
The results that return will include all attributes on the Project Object with the word "Period" in it, but it will also include the "Per-Period Metrics" Object, and all attributes underneath that Object, even though the attributes don't include the word "Period" within them.
Clarity Any Relesae
This is working as designed. Using a search of a word included in an Object will also include the attributes under that Object.
