Totaling a Hierarchy Split Across Multiple Data Sets

[Anonymous]

I am reporting on hierarchical data. The hierarchy has five levels.  I have five data files, one for each level of the hierarchy.  Each line of data has a parent id which connects that line of data to the parent item which is one level higher in the hierarchy.  Each line of data also has a point value which is the sum of its child point values.  I'm trying to find the point value of the items at the top level of the hierarchy by summing the total of all child (and all grandchild) items.  Something like this:  

Level 1 Item						24
	Level 2 Item					12
		Level 3 Item				6
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
		Level 3 Item				6
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
	Level 2 Item					12
		Level 3 Item				6
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
		Level 3 Item				6
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1
			Level 4 Item			1
					Level 5 Item	1

What is the best way to accomplish this?

Hi  @Anonymous ,

You can use matrix visual to work on it.

Hi @Anonymous

Would it be by merging files one by one from the top to the lowest child file and then group?

Kind regards,
