How To Fix RSDD746 - The block characteristic is NOT in the aggregate. Performance warning

RSDD746 - Overview

• Message type: E = Error

• Message class: RSDD - Message class for data manager

• Message number: 746

• Message text: The block characteristic is NOT in the aggregate. Performance warning

What causes this issue?

The block characteristic is NOT in the aggregate, because the BLOCKSIZE
is so small that no characteristic was found in the aggregate that has
enough instances to form enough blocks. As a consequence, the technical
characteristic CHANGEID is used to write "artificial" blocks into the F
table of the aggregate. These then have to be compressed. If they are
not compressed, the read performance for this aggregate is reduced.
Try a larger value for BLOCKSIZE or change the aggregate definition so
that a smaller aggregate can also be used (clever use of the aggregate
tree!).

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

  The SAP error message RSDD746, which states "The block characteristic is NOT in the aggregate. Performance warning," typically occurs in the context of SAP BW (Business Warehouse) when you are working with aggregates in your InfoCubes or when executing queries that involve aggregates.
  
  Cause:
  This warning indicates that a characteristic used in a query or report is not included in the aggregate that is being accessed. When a characteristic is not part of the aggregate, the system may need to access the detailed data in the InfoCube instead of the pre-aggregated data, which can lead to performance issues. This can happen due to:
  
  Missing Characteristics in Aggregate: The characteristic in question was not included when the aggregate was created.
  Changes in the Data Model: If the data model has changed (e.g., new characteristics added), the existing aggregates may not reflect these changes.
  Query Design: The query may be designed in such a way that it
