How to display single record from Joined data source on Form

Hi All,

I need to join two data sources in a form where I have to get only one record from joined data source

I have a table say Table 1

Field1     

A           

B  

Table 2

Field 1          Field 2

A                   XYZ

A                   JKL  (latest record)

B                   123

B                    456  ( latest record)

The two tables are in same grid and the form expectation is

field1        field2

A               JKL

B               456

Please tell me a way to reach the expectation.

Thanks in advance
