Hello
I am trying to replicate this pivot table with the values as running total in the monthly columns.
(see screenshot)
The incremental is added (or deducted each month). For example- my data has Lookup ID 50 (row 5) with a value of £6589 at December (the start of 2022). In January, they had a net movement of -£6589, hence the january value of 0.

Thanks
