Hi sanrajbhar ,
First create an index column in table B;
Then create a calculated column as below:
Column = var _start=CALCULATE(MAX('Table B'[Column 2]),FILTER('Table B','Table B'[Column 1]="Start chainage")) var _index=CALCULATE(MAX('Table B'[Index]),FILTER('Table B','Table B'[Column 2]=_start)) var _end=CALCULATE(MAX('Table B'[Column 2]),FILTER('Table B','Table B'[Index]=_index+1)) var _chain=CALCULATE(MAX('Table A'[Column2]),FILTER('Table A','Table A'[Column1]="Chainage")) Return IF('Table A'[Column1]="Chainage", IF(_chain>=_start&&_chain<=_end,CALCULATE(MAX('Table B'[Column 2]),FILTER('Table B','Table B'[Index]=_index-1)),BLANK()))And you will see:

You will need to set up your tables by columns first (pivot them in Power Query).
Then you can use a measure to "filter" IDs by the criteria you need.can you share actual sample data (with more IDs) instead of an image?

thanks for reply. here IDs are not important. I need to match if chainage is between chainage_start and chainage_end and do the joins.
