    Hello Lora_0121 , 

    Expand - Allows you to select specific columns from the related table and add them to your primary query as new columns.

    Aggregate - Allows you to perform aggregate calculations (such as Sum, Average, Count, Min, Max, etc.) on columns from the related table and return a single summarized value for each match.

    If you find this helpful , please mark it as solution which will be helpful for others and Your Kudos/Likes ๐Ÿ‘ are much appreciated!

     

    Thank You
