Hi. I'm trying to do something different about the cases exposed. 

I have a table that need an increase index when I have some change between three columns. I mean: 

Worker	Fecha	Valor	Index
A	16/04/2018	TRUE	1
A	16/04/2018	TRUE	1
A	16/04/2018	FALSE	2
A	16/04/2018	TRUE	3
B	15/04/2018	TRUE	4
B	16/04/2018	FALSE	5
B	16/04/2018	TRUE	6
B	16/04/2018	TRUE	6

Starting by 1 in each change of first 3 columns I need to increase the index. I'm trying with all the answer from this post but I can't find the solution. 

Other possibility is to save the last combination and the last index in a parameter or another table, but I can't find how to save it in a parameter or table.

In Excel is very easy because yo can calculate from the information in the last cell, but here I can't. 

The excel formula could be: 

=SI(A2=A1;SI(C2="FALSE";SI(C1="FALSE";E1;E1+1);SI(C1="FALSE";E1+1;E1));E1+1)

Yes, that's possible. No use for the grouping in this case, as your index shall continue to run. The only thing you need here is a reference to your previous row. For performance reasons, I recommend this method:
