• What is the cause and solution for SAP error message NRSCNV187 - Run SE14 in parallel: '&1' ?

  The SAP error message NRSCNV187 typically indicates that there is an issue related to the database table conversion or adjustment process, specifically when running the transaction SE14 (Database Utility) in parallel. This error can occur when multiple processes are trying to access or modify the same database objects simultaneously, leading to conflicts.
  Cause:
  
  Parallel Execution: The error arises when multiple instances of the SE14 transaction are executed in parallel for the same database object, which can lead to locking issues or conflicts.
  Database Locking: The database may have locks on the objects being modified, preventing other processes from accessing them.
  Inconsistent State: If the database objects are in an inconsistent state due to previous operations, it may lead to this error when trying to run SE14.
  
  Solution:
  
  Single Execution: Ensure that SE14 is not being executed in parallel for the same database object. Only one instance should be run at a time for a specific table or object.
  Check Locks: Use transaction codes like SM12 (to check for locks) and SM21 (to check system logs) to identify any locks that may be causing the issue. If locks are found, you may need to wait for them to be released or resolve them.
  Run in Background: If you need to run SE14 for multiple objects, consider running them in the background rather than in parallel.
  Database Consistency Check: Ensure that the database is in a consistent state. You may need to perform a consistency check or repair any inconsistencies before proceeding.
  Consult Documentation: Refer to SAP Notes or documentation related to the specific version of SAP you are using for any known issues or additional troubleshooting steps.
