• What is the cause and solution for SAP error message SABP_KEY_REDUNDANCY001 - Check whether one of the keys can be deleted ?

  The SAP error message SABP_KEY_REDUNDANCY001 typically indicates that there is a redundancy in the key fields of a particular object or data structure. This error often arises when you are trying to create or modify a key that already exists in the system, leading to conflicts or duplications.
  Cause:
  
  Duplicate Key Entries: The most common cause of this error is that there are multiple entries in the database that share the same key values, which violates the uniqueness constraint of the key.
  Incorrect Configuration: Sometimes, the configuration of the data model or the way keys are defined can lead to redundancy issues.
  Data Migration Issues: If data has been migrated from another system, it may have introduced duplicate keys that were not present in the original system.
  
  Solution:
  
  Check Existing Keys: Review the existing entries in the database to identify any duplicates. You can use transaction codes like SE16 or SE11 to view the relevant tables.
  Delete Redundant Keys: If you find that there are indeed duplicate keys, determine if one of them can be safely deleted. Ensure that the key you are considering for deletion is not being used elsewhere in the system.
  Modify Key Configuration: If the redundancy is due to incorrect configuration, you may need to adjust the key definitions in the relevant customizing settings.
  Data Cleansing: If the issue arose from data migration, perform data cleansing to remove or consolidate duplicate entries.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module you are working with for any additional guidance on handling key redundancy issues.
