Hi there.
I want to share how I solved this problem, maybe it will help someone in the future.
This is nothing new, all taken from the tutorial (http://wiki.eclipse.org/Scout/Tutorial/5.0/Minicrm/Write_the_second_page), and the only thing that I want to pay attention to when performing this task in the future.

For example, I have two TablePages:
- TalonSotrsTablePage as a Parent TablePage
where two important fields:
- YearsColumn
- MonthsColumn

- TalonSotrDetailsTablePage as a Child TablePage
where I also have the fields:
- YearsColumn
- MonthsColumn

then I want to pass the field values Years and Months to the Child TablePage.
I created two property beans (Years and Months) in the TalonSotrDetailsTablePage ChildPage.

Important!
I checked out to the fields Years and Months on the TalonSotrDetailsTablePage ChildPage as the primary key:

On execCreateChildPage metod of the ParenPage TalonSotrsTablePage I wrote as follows:

@Override
protected IPage execCreateChildPage(ITableRow row)  throws ProcessingException {
	TalonSotrDetailsTablePage childPage = new TalonSotrDetailsTablePage();
	
        childPage.setYears(getTable().getYearsColumn().getValue(row));
	childPage.setMonths(getTable().getMonthsColumn().getValue(row));

	return childPage;
}

On execLoadData metod of the ChildPage TalonSotrDetailsTablePage I wrote as follows:

@Override
protected void execLoadData(SearchFilter filter) throws ProcessingException {
	importPageData(SERVICES.getService(ITalonsOutlineService.class)
        .getTalonSotrDetailsTableData(getYears(), getMonths()));
}

Then I created with wizard on my OutlineService new service operation as follows:

Conclusion:
When you pass significant fields from the Parent TablePage to the Child TablePage you must:
- Have same fields on the ChildPage;
- Mark this same fields as the Primary Keys;
- Create (for passed fields) appropriate property beans on the ChildPage;

That's all.

P.S.:
You can say that I repeated the tutorial, yes of course.
But by this post I wanted to focus attention on using the primary key properiie of columns, which is not indicated in the tutorial.
And on this problem I lost a lot of time. Sad

I would be glad if someone can help in the future. If I made a mistake somewhere or done wrong I will be glad to hear

Thank you for sharing this here. Your analysis is absolutely correct and I hope it will help other.

It is difficult to cover each aspect of the Framework in a simple tutorial.

Thank you Jérémie,
for your reply.

First of all, we should thank Scout Team and BSI AG for these tutorials! Tutorials are self-sufficient to get an idea and begin to create a ready-made programs.
Of course, the ideal is nothing in the world. And of course, pleased that there is a Scout forum and Scout Contributers that make the platform better.
Thanks to all !
