Data Display in the subreport of the crystal report! Problem collection!

Problems with self-reporting:
-------------------------------
The main report data source is the department table field: organid, organname. [The field is displayed in the Report]
Fields of the table related to employee salaries in the data source of the subreport: empid, empname, organid, organname, paymoney1, paymoney2, and paymoney3. [fields are displayed in the Report]

The joined connection field is organid.
----------------------------------
Problem:
Only organid and organname fields are displayed in the subreport;
Why are the data subreports of empid, empname, paymoney1, paymoney2, and paymoney3 not displayed ????? All retrieved data sources have data !!?!
--------------------------------------------
Later I remembered that the ADO dataset fields in my primary and subreports use the same dataset. XSD. So don't make such a fool-like mistake. None of the above problems will happen ..
---------------------------------------------------
Other questions on the Internet:

I have created four subreports in the main report, requiring that my work experience/educational experience/training experience/skills be displayed.
However, the displayed sub-reports do not show the educational experience after the work experience is displayed, and the records are repeated. Why ??? How should we control and design reports 〉?
-----------------------------
Positive Solution:

When you create a subpartition table, you have an option of "show the subpartition table as needed". After you select this table, as you said, as a response, it is shown as a response. You need to expand another response area to open a subpartition table.

BTW, it is suggested that you do not place the sub-tables in the metadata. This type of lattice is not good, and the tables are also redundant and easy to read.
