Hi 
I am trying create an index for a CoverageCategory that is inside a relationship-model with multiplicity of 999.999.
With CompCoverageCategorieId I am trying to calculate the Id with CurrentRepitition:
It seems that this only works on groups with multiplicity.
Do you know how to solve this a different way?
Kind regards,
Timo
Hi @timo-thin-buffer
You are modeling your Computation Rule in the Group “ContractCoverageCaetegory_r…”
This sets the starting point for the relative path (see here).
To reference this Group in the Computation Rule you need to use
CurrentRepetition(RuleGroup)
as documented at the end of this section.
Thanks a lot! This helped very much 
Sorry for not remembering / scanning the docs not good enough
