CX_DATA_ANALYSIS
The data analysis object manages 3 dimensions: the time, warehouse, item group.
The time (year and month) are managed directly by the user, access to the warehouse and article group (structure object) objects is via their CX_DATA_ANALYSIS_ACCOUNT accounts.
Each document is therefore booked in the data cube with the 3 (even 2-dimensional) dimensions time. Warehouse and article group.
