Problem with grouping

[erick-flores]

Hello all

I am trying to create a big report with diferent groups. I want to
create 6 groups. I tried using the "Create Report Using Wizard" but i
did not work, it said your report has so many fields...it just didnt
work. Can somebody help/guide me here? what is my best option to create
this report?

Overview of Report:
I have 18 tables. Each table is link to another one. Table1 - Table2.
Table2 - Table3. Table3 - Table 4. Table 4 -
Table5-Table6-Table7-Table8-Table9 ...etc. I want to create groups for:
- Table2 (group1)
- Table3 (group2)
- Table4 (groups3)
- Table5-Table6-Table7-Table8-Table9 (group4)
- Table10-Table11-Table12-Table13-Table14-Table15 (group 5)
- Table16-Table17-Table18 (group6)

And I will be displaying only 3 fields for each group, execpt for the
first two groups (5-6 fields)

I am pretty familiar creating reports, but this one got me. I need help
pleaseeeeee

Thanks
