• What is the cause and solution for SAP error message RSTRAN018 - Generation status of transformation &1 will be reset ?

  The SAP error message RSTRAN018 indicates that the generation status of a transformation will be reset. This typically occurs in the context of data transfer processes, particularly when working with SAP BW (Business Warehouse) or SAP BW/4HANA.
  Cause:
  The error message can be triggered by several factors, including:
  
  
  Changes in the Transformation: If there have been changes made to the transformation (e.g., modifications in the mapping, data source, or target), the system may reset the generation status to ensure that the transformation is up-to-date.
  
  
  Inconsistencies in the Data Model: If there are inconsistencies or issues in the data model, such as missing or incorrect data sources, the transformation may not be able to generate correctly.
  
  
  Transport Issues: If the transformation has been transported from one system to another (e.g., from development to production), there may be issues with the transport that cause the generation status to be reset.
  
  
  System Updates or Changes: Updates to the SAP system or changes in the underlying database can also lead to this error.
  
  
  Solution:
  To resolve the RSTRAN018 error, you can take the following steps:

  Re-generate the Transformation: Go to the transformation in the SAP BW system and attempt to regenerate it. This can often resolve issues related to the generation status.
  
  
  Check for Inconsistencies: Use the SAP BW tools to check for inconsistencies in the data model. This may involve checking InfoObjects, DataSources, and other related components.
  
  
  Review Transport Logs: If the transformation was recently transported, check the transport logs for any errors or warnings that may indicate issues during the transport process.
  
  
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error message. SAP frequently updates its knowledge base with solutions for known issues.
  
  
  System Restart: In some cases, a system restart may help clear temporary issues that could be causing the error.
