Help comparing dates between tables
A couple of things you can try:
Either do a MERGE in the Power Query Editor and choose LEFT ANTI as the Join Kind. If you Merge as new table, this will give you a 3rd table that will show the values in A that are not in B. Before you do this you will need to create a new merged column that has all the data that should be the same in each table, so in your case all 4 columns displayed.
Or you could use dimension DATE, Employee and Leave Type tables in the Power BI report that can link the two tables and try to reconcile that way by using the columns from the dimension tables and create a measure that calculates the difference in hours between source A and B. Add this as a filter to the visualization and filter for when the difference is not equal to 0.
