• Message type: E = Error

• Message class: RSAR - Data Transfer and Metadata Maintenance

• Message number: 325

• Message text: Transfer structure prefix for source system & is not defined

What causes this issue?

A prefix is defined for the source system for determining cross-system u
nique transfer structure names. This prefix is not defined between your
source system &V1& and warehouse &V2&. There was an error when creating
the source system.

How to fix this error?

If you have not yet loaded data from this source system, delete the sour
ce system and then recreate it.

• What is the cause and solution for SAP error message RSAR325 - Transfer structure prefix for source system & is not defined ?

  The SAP error message RSAR325 indicates that there is an issue with the transfer structure prefix for a source system in the context of SAP BW (Business Warehouse) data transfer processes. This error typically arises when the system is unable to find the necessary transfer structure for the specified source system.
  Cause:
  
  Missing Transfer Structure: The transfer structure for the specified source system is not defined in the SAP BW system.
  Incorrect Configuration: There may be a misconfiguration in the source system settings or the data source settings.
  Transport Issues: If the transfer structure was recently transported from another system, it may not have been properly imported or activated.
  Source System Not Properly Defined: The source system may not be correctly defined in the BW system.
  
  Solution:
  
  
  Check Transfer Structure:
  
  Go to the Data Warehousing Workbench (transaction RSA1).
  Navigate to the relevant InfoSource or DataSource and check if the transfer structure is defined.
  If it is missing, you may need to create or activate the transfer structure.
  
  
  
  Define Transfer Structure:
  
  If the transfer structure is not defined, you can create it by going to the DataSource in the source system and ensuring that the transfer structure is generated.
  Use transaction RSA6 to check the DataSources and their corresponding transfer structures.
  
  
  
  Check Source System Configuration:
  
  Ensure that the source system is correctly configured in the BW system. You can check this in the transaction RSC1 (for source system configuration).
  Verify that the source system is active and that the connection is working properly.
  
  
  
  Transport Issues:
  
  If the transfer structure was recently transported, check the transport logs to ensure that it was successfully imported.
  If there were errors during transport, you may need to re-transport the relevant objects.
  
  
  
  Re-activate DataSource:
  
  Sometimes, simply reactivating the DataSource can resolve the issue. You can do this in transaction RSA1 by selecting the DataSource and choosing the "Activate" option.
  
  
  
  Check for Notes and Patches:
  
  Check the SAP Support Portal for any relevant notes or patches that may address this issue. Sometimes, specific versions of SAP BW may have known issues that are resolved in later patches.
