Hello everybody!

I have a structure: a Data-Messages class with fields:
- ID Message
- Message
There is also a Data-Attachment class with fields:
- ID Attach
- ID Message
- Attach link

I need to create a data page that returns this structure. Each message can have several attachments.
In my data page, I use source as a report definition. But when setting up, I have a duplicate of the objects of the Data-Message class. Those. a message entry is created for each attachment.
It seems to me that I have chosen the wrong approach to the task.

Please advise solutions. I will be very glad to any advice.
