May I know when we perform a multi-group test, we need to check functional equivalence for both reflective and formative constructs, or only reflective constructs? In the MPLUS manual, it seems that all examples relate to reflective constructs.
If you have formative constructs, they should exhibit measurement invariance across groups if you plan to compare their parameters across groups. The steps would be the same as for reflective constructs.
