Iterative dax column

Hello Vaibhav3008,

If you can add an additional column called "row number", your problem may be solved like this:

Here's the [DAX] code in the text format for convenience:

projection = 
VAR current_row_number = [row number]
VAR last_inv_value_index = MAXX ( FILTER ( ALL ( data ), NOT ( ISBLANK ( data[inventory value] ) ) ), [row number] ) 
VAR base = LOOKUPVALUE ( data[inventory value], data[row number], last_inv_value_index )
VAR surplus = CALCULATE ( SUM ( data[to be added value] ), ALL ( data ), data[row number] > last_inv_value_index, data[row number] <= current_row_number )
VAR result = IF ( ISBLANK( data[inventory value] ), base + surplus, BLANK () )
RETURN result

 If a new column is not an option, you will need a more complex solution.

Best Regards,

Alexander
