About Specifying Indentation
Using the Indentation command in the TBL REGIONS menu, you can specify an indentation for report data in recursive repeat regions. The cell to which you apply the indentation must be in a repeat region that has Recursive specified as one of its attributes, and should contain a recursive report parameter symbol (such as "asm.mbr.name"), although this is not a requirement. If you select a cell that does not contain a recursive parameter, the system informs you, but it indents the data if you specify a value.
Creo Parametric expresses indentation for a repeat region cell using a number between 0 and 100. The number indicates the value in characters (at the default text size) by which that data is indented in a recursive repeat region. Creo Parametric increments the indentation by the specified amount at each new level in the table.
