• What is the cause and solution for SAP error message /SCMTMS/PLANNING_SET101 - Selection without index time may lead to long runtimes ?

  The SAP error message /SCMTMS/PLANNING_SET101 indicates that a selection operation is being performed without the use of an index, which can lead to long runtimes during data retrieval or processing. This message is typically encountered in the context of SAP Transportation Management (TM) or similar modules where large datasets are involved.
  Cause:
  The error is triggered when a query or selection is executed on a large dataset without the benefit of an index. This can happen due to:
  
  Lack of appropriate indexing on the database tables being queried.
  Use of complex selection criteria that do not leverage existing indexes.
  The selection criteria may be too broad, causing the system to scan the entire table instead of using an index.
  
  Solution:
  To resolve this issue, consider the following steps:
  
  
  Review Database Indexes:
  
  Check if the relevant database tables have appropriate indexes defined. If not, consider creating indexes on the columns that are frequently used in selection criteria.
  
  
  
  Optimize Selection Criteria:
  
  Refine the selection criteria to be more specific. This can help the system utilize existing indexes more effectively.
  Avoid using wildcard characters or broad ranges that may lead to full table scans.
  
  
  
  Analyze Query Performance:
  
  Use transaction codes like ST05 (SQL Trace) or SE11 (Data Dictionary) to analyze the performance of the queries being executed. This can help identify which parts of the query are causing performance issues.
  
  
  
  Database Statistics:
  
  Ensure that database statistics are up to date. Outdated statistics can lead the query optimizer to make suboptimal decisions regarding index usage.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes or updates that may address performance issues related to the specific version of SAP TM you are using.
  
  
  
  System Configuration:
  
  Review system configuration settings that may impact performance, such as buffer sizes and memory allocation.
  
  
  
  Engage SAP Support:
  
  If the issue persists, consider reaching out to SAP Support for further assistance. They may provide specific recommendations based on your system configuration and usage patterns.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and ST22 (Dump Analysis) for further investigation.
  Performance Tuning: Regularly monitor and tune the performance of your SAP system to prevent similar issues in the future.
  Documentation: Refer to SAP documentation for best practices on database performance and query optimization.
  
  By addressing the underlying causes of the error message, you can improve the performance of your SAP system and reduce the likelihood of encountering long runtimes during data selection operations.
