// Power Query / M function to add a Running Sum or Running Count. 
// Expects a numeric column named Input to exist in the table. To achieve a Running Count, set the value of Input to 1 on every row. 
// Call by using the UI to "Group By" with an "All Rows" operation. Then edit the generated "Grouped Rows" step to change: "each _" to: "each fnAddRunningSum ( _ )"
// Then expand the All Rows table-type column to get the added column named "Running Sum"

let
    Source = Table.Buffer(MyTable),

-- Having extracted Xero data into BigQuery (via Stitch Data), extracting the Invoice Line details is still quite tricky.
-- On the invoices table, the invoice lines are stored as a nested JSON object: lineitems
-- The following query produces a row for each Invoice Line, and also unpacks Tracking fields

-- this line handles the easy single-field selections
SELECT invoiceid, invoicenumber, lineitems.lineamount, lineitems.description as linedescription
-- unpack the sub-nested lineitems.tracking nodes for each invoice, and return the option field for a specific name. 
-- LIMIT 1 ensures we only return the first match. SQL will break if more than one result is returned.
, ( SELECT option from UNNEST ( lineitems.tracking ) WHERE name = 'Studio' LIMIT 1) as Studio
-- repeat the unpack for another tracking name

// Trims in the style of the Excel TRIM function - embedded whitespace is trimmed to a single space.
// This variation accepts null values in the text parameter, in which case it returns an empty string.
