Up to now the column header of ERP columns had no coloring, so that at single-line projects the belonging to a group could not be recognized.

As of V11 SP7 a fine line is displayed now.

Single-line project: Belonging to a group is signalized by a fine colored line.

In settings dialog, reachable via Extras menu -> Settings... -> Table menu -> Show ERP colors in header, you can determine, if the line is also shown at multiline projects. Per default, the option is activated.

Show ERP colors in header

Note At single-line projects the coloring is always performed regardless of whether the option is activated or not.

"Show ERP colors in header" activated
