How To Fix RSDD744 - The aggregate is 'flat', that is, it has less than 14 characteristics

RSDD744 - Overview

• Message type: E = Error

• Message class: RSDD - Message class for data manager

• Message number: 744

• Message text: The aggregate is 'flat', that is, it has less than 14 characteristics

What causes this issue?

Flat aggregates can be filled directly with database tools, this means a
detour through the ABAP is not necessary and DIMIDs do not have to be
retrieved because the characteristic is exactly one dimension and the
dimension tables are replaced with a view of the SID table of the
characteristics (a "Line Item" Dimension). An exception is the package
and unit dimensions, which are both not split into line item dimensions.
Flat aggregates provide performance advantages during data loading
(rollup) and possibly also during reporting.
For technical reasons, flat aggregates are not possible for non-
cumulative cubes!

• What is the cause and solution for SAP error message RSDD744 - The aggregate is 'flat', that is, it has less than 14 characteristics ?

  The SAP error message RSDD744 indicates that the aggregate you are trying to create or use is classified as "flat," meaning it has fewer than 14 characteristics. This can occur in the context of SAP BW (Business Warehouse) when working with aggregates in InfoCubes.
  
  Cause:
  
  
  Characteristics Count: The primary reason for this error is that the aggregate you are working with has fewer than 14 characteristics. In SAP BW, aggregates are used to improve query performance by pre-calculating and storing summarized data. However, SAP has a limitation that aggregates with fewer than 14 characteristics are considered flat and cannot be processed in the same way as more complex aggregates.
  
  
  Design of the InfoCube: The design of the InfoCube may not have enough characteristics defined, or the specific aggregate you are trying to create is not designed to meet the minimum requirement.
  
  
  
  Solution:
  
  
  Review Aggregate Design: Check the design of the aggregate and ensure that it
