• What is the cause and solution for SAP error message LTR2_RN_CHECK052 - Mapping conflict due to number range level changed in receiver ?

  The SAP error message LTR2_RN_CHECK052 indicates a mapping conflict due to a change in the number range level for a receiver in the context of SAP's Logistics Execution (LE) or related modules. This error typically arises when there is a mismatch between the expected number range and the actual number range defined in the system for a specific object or document type.
  Cause:
  
  Number Range Configuration Change: The number range for a specific document type or object has been altered, which can lead to conflicts if the system is trying to map an existing document to a new number range configuration.
  Inconsistent Data: There may be existing data that does not conform to the new number range settings, leading to conflicts during processing.

  Solution:
  
  
  Check Number Range Configuration:

  Adjust Mapping:
  
  If the number range has been changed intentionally, you may need to adjust the mapping logic in your configuration or custom code to accommodate the new number range settings.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on the data to identify any records that may be causing the conflict. This can often be done through standard SAP reports or custom queries.
