• What is the cause and solution for SAP error message RJ190 - The name of DataSource & is too long to extract deltas ?

  The SAP error message RJ190 indicates that the name of a DataSource is too long for the system to handle when attempting to extract delta data. This typically occurs in the context of SAP BW (Business Warehouse) or SAP Data Services when working with data extraction processes.
  Cause:
  The primary cause of this error is that the DataSource name exceeds the maximum length allowed by the SAP system. In SAP BW, there are specific limitations on the length of identifiers, including DataSource names, which can lead to this error when the name is too long.
  Solution:
  To resolve the RJ190 error, you can take the following steps:
  
  
  Rename the DataSource: 
  
  Shorten the name of the DataSource to ensure it complies with the length restrictions. The maximum length for DataSource names is typically 30 characters, but it is advisable to keep it even shorter to avoid similar issues in the future.
  
  
  
  Check Naming Conventions: 
  
  Ensure that the naming conventions used for DataSources are consistent and within the limits set by SAP. This includes avoiding unnecessary prefixes or suffixes that could contribute to excessive length.
  
  
  
  Review DataSource Configuration: 
  
  After renaming, review the configuration of the DataSource to ensure that all references and settings are still valid and functioning correctly.
  
  
  
  Test the Extraction: 
  
  Once the DataSource has been renamed, test the delta extraction process again to confirm that the error has been resolved.
