Primavera P6: Hide Blank Activity Code, No Activity Code at the summary band

When grouping activities by Activity Code and the activities are not fully assigned all the Code, the summary band will show “No <<Activity Code name>>” like the following picture.

In order to hide these unnecessary words, there is a workaround.

Create a new code value in which the description is a blank space or a simple hyphen “_”

Assign it to the necessary activities then the layout looks better.
