Problem:
A common requirement in Business Central customization is to consolidate General Journal Lines.
In this real-world case (from a Facebook developer question), the requirement was to:
Read Gen. Journal Lines from a Source Batch
Group lines by: Posting Date, Account No. & Dimension Set ID
Sum the Amount field
Insert consolidated lines into a Target Batch
Delete the source lines after consolidation

Solution:
The clean and scalable solution is to use a Query Object with:
Grouping on Posting Date, Account No., Dimension Set ID
Aggregation (SUM) on Amount fields
AL code to loop through Query results instead of raw records

Result:
Accurate consolidation
Cleaner AL code
Better performance
No duplicate logic
Easy to maintain and explain

In this video, I demo the actual working code, explain each part of the Query Object, and show how the consolidated lines are inserted into the target Gen. Journal Batch.
