Performant trial balance Excel reports

[mynjj]

Summary

A different approach to calculate trial balance excel reports. Instead of looping over accounts, dimensions, and business units and querying, have query objects that do the same in a single query (or multiple passes of such query).

Main idea of how it works: Two-pass approach

Since the report needs Starting Balance, Net Change, and Ending Balance (Balance at Date), and a single SQL aggregation can only give a sum up to a given date, the query is executed twice:

1. First pass - filter PostingDate <= EndDate (i.e. ..EndDate):

   • For each group (Account, Dim1, Dim2) returned by the query, a buffer record is inserted.
   • The summed amount is written into both Balance (ending balance) and Net Change (as a temporary placeholder).

2. Second pass - filter PostingDate <= StartDate - 1 (i.e. ..StartDate - 1):

   • For each group returned, the matching buffer record is found (or created if missing).
   • Starting Balance is set to the summed amount.
   • Net Change is adjusted: Net Change := (Balance at EndDate) - (Balance at StartDate - 1).

3. End-Total fixup - After both passes, End-Total accounts are computed by summing the buffer records whose "G/L Account No." falls within the End-Total's Totaling range. This is required since the query will only return entries for Posting type accounts

And the same/analogous way for reports that use Business Unit (Consolidation report), or budget entries.

Several issues with the approach were also fixed (see tests)
