How To Fix RSD_TREX513 - Suggest delta indexes for certain indexes ('&1')

RSD_TREX513 - Overview

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 513

• Message text: Suggest delta indexes for certain indexes ('&1')

Description
It is useful to create a delta index for large indexes that are often
updated with new data. New data is not written to the main index, but to
the delta index. This can significantly improve the performance of
indexing, since the "OPTIMIZE" step must only be executed on the smaller
amount of data from the delta index. The data from the delta index is
used at the runtime for the query.
The system determines the proposals from the statistics data: proposals
are indexes that received new data more than ten times during the last
ten days. A prerequisite for these proposals is that the statistics for
the InfoCube are switched on.
A "MERGE" should be executed for data in the main index and delta index
at regular intervals (see test "Size of Delta Index").
Repair
In repair mode, the system sets the <ZK>Has Delta Index</> property for
the proposed indexes. The delta index is created when the data is next
loaded for this index.

• What is the cause and solution for SAP error message RSD_TREX513 - Suggest delta indexes for certain indexes ('&1') ?

  The SAP error message RSD_TREX513 indicates that the system is suggesting the creation of delta indexes for certain indexes. This typically occurs in the context of SAP BW (Business Warehouse) when working with InfoProviders that are based on the SAP HANA database or when using the TREX search engine.
  
  Cause:
  The error message is triggered when the system detects that certain indexes are not optimized for delta processing. Delta indexes are used to improve the performance of data retrieval operations by allowing the system to quickly access only the changes (deltas) made since the last data load, rather than scanning the entire dataset.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Create Delta Indexes:
  
  Go to the relevant InfoProvider in the SAP BW system.
  Check the settings for the indexes that are suggested in the error message.
  Create delta indexes for the specified InfoProviders. This can usually be done through the Data Warehousing Workbench (transaction
