    HI Anmol ,

     

    Let me know  if this works for you.

     

     

     

    Create Calculated Columns

     

    Previous_Value = CALCULATE(
    MAX('Table'[Input_Priority]),
    FILTER('Table','Table'[Task_Id] = EARLIER('Table'[Task_Id]) && 'Table'[Request_DateTime] < EARLIER('Table'[Request_DateTime] )))
     
     
    RANK_ = RANKX(
    FILTER('Table',
    'Table'[Task_Id] = EARLIER('Table'[Task_Id])
    ),
    'Table'[Request_DateTime] 
    ,,ASC,Dense)

Hi Anmol 

Can you show a sample of the table you are using and explain with an example based on that data/table what you would need?

Please mark the question solved when done and consider giving kudos if posts are helpful.

Contact me privately for support with any larger-scale BI needs, tutoring, etc.

Cheers

That's how the data looks like, im just looking for a calculated column that gives previous 'input_priority' only after sorting the data on 'task_id' and 'request_datetime'.
