Power Query - Create a Matrix from a Table

Martin Kerr 21 Reputation points

I am reasonably new to Power Query and I'm trying to figure out the most efficient way to perform the transformation shown in the attached screen grab.

Currently I am loading the source table in to Power Query and doing the following:

  1. Load the Source Table into Power Query
  2. Create a Master Query containing all the data from the source table
  3. Create a second query called Parent Task 1 by referencing the Master Query and filtering for Parent Task = Parent Task 1
  4. Create a third query called Parent Task 2 in the same manner as second query
  5. Create a fourth query called Parent Task 3 in the same manner as second query
  6. Create a fifth query containing only unique Parent Tasks
  7. Merge queries 2 to 5 to create required format.

I'm really hoping there is a more efficient way to do this. Any suggestions?
