To create or modify a link, the following conditions
must be respected:
- You can
only link dimensions, attributes and hierarchies.
- The
expressions to link must have the same data type.
- Each
expression that you link to must be from a different data provider.
- The
expressions that you link to must not be already used in another link.
- You
cannot link to expressions that have been stripped (no query stripping
allowed).
- The
expressions must be compatible.
About compatibility:
- All
custom formulas and variables will be considered as compatible to any other
expressions and then ignored.
- Measures
are always compatible with everything.
- If dimension A is linked, then A is compatible with all
expressions in the flow lists that contain the link.
- Two
dimensions or attributes from different flow lists are incompatible. Except
when a dimension in linked, as mentioned above.
Below are the main tasks you can perform on the links of a report.
