Need solution

Hi Tejas8275 
There is a solution in Power Query to add a grouped index. Curbal has a video about it here.
Add index to subgroups in Power Query - YouTube

So in your data you would do an advanced grouping by Column A & Column B. Select All rows.

Then you would add an index column with a custom function

= Table.AddColumn(#"Grouped Rows", "Index", each Table.AddIndexColumn([Data],"Index",1,1))

Then remove the other column and expand the index column. Your data will look like this.

Then you can select only the the rows that are either accepted or have an index of 1 with a new step.

= Table.SelectRows(#"Expanded Index", each ([Index.1] = 1 or [ColumnB] <> "Rejected"
))

I hope this helps.
