• What is the cause and solution for SAP error message RSAR755 - Communication structure & was deactivated ?

  The SAP error message RSAR755 indicates that a communication structure has been deactivated in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence). This typically occurs when there are issues with data transfer processes, especially when using the SAP BW system to extract data from various sources.
  Cause:
  
  Deactivation of Communication Structure: The communication structure that is required for data transfer has been deactivated. This can happen due to various reasons, such as changes in the data model, updates to the system, or manual deactivation by a user.
  Data Source Changes: If the data source has been modified or if there are inconsistencies in the data model, it may lead to the deactivation of the communication structure.
  Transport Issues: If there are transport requests that have not been properly imported or have caused inconsistencies, this can also lead to the deactivation of communication structures.
  
  Solution:
  
  
  Reactivate the Communication Structure:
  
  Go to the transaction code RSA1 (Data Warehousing Workbench).
  Navigate to the relevant data source or InfoSource.
  Check the status of the communication structure and reactivate it if it is deactivated.
  You can also use transaction RSA3 to test the data source and see if it is functioning correctly after reactivation.
  
  
  
  Check Data Source Settings:
  
  Ensure that the data source settings are correct and that there are no inconsistencies in the data model.
  If there have been recent changes to the data source, verify that all necessary adjustments have been made.
  
  
  
  Review Transport Requests:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings that might indicate what went wrong.
  Ensure that all necessary objects have been transported correctly.

  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error message. There may be patches or updates that can resolve the issue.
  
  
  
  System Restart: In some cases, a system restart may help in resolving temporary issues related to communication structures.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1, RSA3, and RSC1 (for InfoSource maintenance).
  SAP BW Documentation: Review SAP BW documentation for best practices on managing data sources and communication structures.
