How To Fix RSD_TREX547 - Estimate storage requirements of fact index

SAP Error Message - Details

• Message type: E = Error

• Message class: RSD_TREX - Messages from TREX Aggregate Area

• Message number: 547

• Message text: Estimate storage requirements of fact index

Description
This test estimates the size of the fact index of the BWA index. In
doing so, the system analyzes the data in the fact table and provides a
projection.
Note that if data distribution is poor, the actual memory consumption
can deviate from the projected value. A more exact analysis would demand
more time than the time required to rebuild the index, since the number
of different values in the fact table needs to be determined for each
column (COUNT DISTINCT).
Repair
This test has no repair.

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 RSD_TREX547 typically occurs when there is an issue with estimating the storage requirements for a fact index in SAP BW (Business Warehouse) or SAP HANA. This error can arise during the process of creating or modifying InfoCubes or when performing data modeling tasks.
  Cause:
  
  Insufficient Memory: The system may not have enough memory allocated to perform the estimation.
  Configuration Issues: There may be misconfigurations in the BW or HANA settings that prevent the estimation process from completing successfully.
  Data Volume: The volume of data being processed may be too large for the system to handle during the estimation phase.
  System Performance: The overall performance of the system may be degraded due to high load or other resource-intensive processes running concurrently.
  
  Solution:
  
  Check System Resources: Ensure that the system has adequate memory and CPU resources available. You may need to increase the memory allocation for the SAP instance.
  Review Configuration: Check the configuration settings for the BW or HANA system. Ensure that all necessary parameters are set correctly.
  Reduce Data Volume: If possible, try to reduce the amount of data being processed during the estimation. This can be done by filtering the data or working with a smaller dataset.
  Monitor System Performance: Use transaction codes like ST03N or ST06 to monitor system performance and identify any bottlenecks.
  Update SAP Notes: Check for any relevant SAP Notes that may address this specific error. Applying the latest patches or updates can sometimes resolve underlying issues.
  Re-run the Estimation: After making the necessary adjustments, try to re-run the estimation process to see if the error persists.
