I have just tried and got task with indent between 0 and 1 in filter. And group it by Parent Name. And it seems to work. Unless that's not exactly what you are looking for.
Hi Susan,
Try using this as your 'Task Name' column (change it to text mode and replace whatever is there with the below):
descriptionkey=name displayname=Task isInlineEditable=false link.linkproperty.0.name=ID link.linkproperty.0.valuefield=ID link.linkproperty.0.valueformat=int link.lookup=link.view link.valuefield=objCode link.valueformat=val linkedname=direct listsort=string(name) namekey=task.name.abbr querysort=name section=0 shortview=false stretch=100 textmode=true valueexpression=IF({indent}<1,{name},IF({indent}<2,CONCAT(" - ",{name}),IF({indent}<3,CONCAT(" - - ",{name}),IF({indent}<4,CONCAT(" - - - ",{name}),CONCAT(" - - - - ",{name}))))) valueformat=HTML width=150
