Multiple values for multiple fields sharing common id

Question

I'm new to Reporting Services and I need to create report based on a common child id that includes multiple values from multiple fields in several tables. I can combine all the values into one query for a list report; however, this causes the rows to duplicate
multiple times based on the differing fields having multiple values (i.e. report contains various child ids and multiple medication dates/names, multiple health diagnoses with onset dates, multiple health service dates/values, multiple immunization types and
service dates, etc). If I create a list report and try to use various tables, I run into problems with how the tables view the data due to the duplicating child id rows from multiple field values on that child id. If I hide duplicates for these different tables,
I can run into spacing issues from the duplicating rows and/or hiding data that shouldn't be hid.
I need the report to have the basic non-duplicating child info (id, name, basic health info) and then also have various sections that contain fields with numerous values (i.e. section for health issue name and onset dates, section for medication name and
prescription dates, section for health service name and service date, etc). I would want a page break after each child id and would want all the child ids to be viewed/exported for printing purposes at the same time (i.e. not choosing one child id at
a time to print or view the data). I have tried to create one main table on a list report with various subreports on the child id; however, this is hard for my machine to process (it takes forever) and I can only view/export one child id at a time when I use
child id as the report parameter.
Any help you can give this newbie would be greatly appreciate.
Thanks,

Hi simpson213,
According to your description, you have some questions about your report design.
1. How to have non-duplicating child info?
In this scenario, since you don't want to hide the duplicate data, we suggest you filter the duplicated records on query level by using Distinct statement. If you want to do it on report level, you can group
records on chid id and use First() function on other fields. 
Reference: First Function (Report Builder and SSRS)
2. How to  have various sections that contain fields with numerous values?
We can also add these fileds into the child group of child and have them toggled by child id. 
Reference: Add an Expand/Collapse Action to an Item (Report Builder and SSRS)
3. How to add a page break between each child?
Right click on the Row Group(child id)->Page Break->Select between each group instance.
Reference: Add a Page Break (Report Builder and SSRS)
4. How to select multiple child id when rendering report?
When creating parameter, select Allow multiple values in General.

If you have any question, please feel free to ask.
