Smart SAP Assistant

• What is the cause and solution for SAP error message /UI5/MP_CA_APP005 - DataSource to delete is still used: &1, deletion not possible ?

  The SAP error message /UI5/MP_CA_APP005 indicates that a DataSource you are trying to delete is still in use, which prevents the deletion from being completed. This is a common issue when working with SAP UI5 applications and their associated data sources.
  Cause:
  The error occurs because the DataSource you are attempting to delete is still being referenced or utilized by one or more components in the system. This could include:
  
  Active Applications: The DataSource might be linked to active applications or services.
  Data Models: It could be part of a data model that is currently in use.
  Dependencies: Other components or configurations may depend on the DataSource.
  Caching: Sometimes, the system may have cached references to the DataSource.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Identify Dependencies:
  
  Check which applications, services, or components are using the DataSource. You can do this by reviewing the configuration settings in the SAP system or using transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator).
  
  
  
  Deactivate or Remove References:
  
  If you find any active applications or services using the DataSource, you will need to deactivate or remove those references before attempting to delete the DataSource again.
  
  
  
  Check for Active Sessions:
  
  Ensure that there are no active sessions or users currently using the DataSource. You can use transaction SM04 to check active user sessions.
  
  
  
  Clear Cache:
  
  If the DataSource is cached, you may need to clear the cache. This can sometimes be done through transaction SE38 by executing the report RSUI5_CACHE.
  
  
  
  Retry Deletion:
  
  Once you have ensured that the DataSource is no longer in use, try deleting it again.
  
  
  
  Consult Documentation:
  
  If you are still facing issues, consult the SAP documentation or reach out to your SAP Basis or development team for further assistance.
