How To Fix MCEX260 - DataSource &1: Data access using 'Direct Access' not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: MCEX - Extraction Interface LIS/BW

• Message number: 260

• Message text: DataSource &1: Data access using 'Direct Access' not possible

What causes this issue?

Data access for DataSource &V1& is to be performed using the access
method 'Direct Access'. However, this is only possible with a certain
system status:
Data updates must run in transfer mode 'Full' (UPDMODE = F). In
addition, either the request number has to use the access method 'Direct
Access' (REQUNR = DIRECT_ACCESS) or the data access has to be performed
as a remote call via BW (REMOTE_CALL = X).

System Response

The current system status does not meet the prerequisites defined above
and data access is not performed.

How to fix this error?

Ensure that the data access occurs using an ODP-based query.
If you want to test the data access for DataSource &V1& using the access
method 'Direct Access' via RSA3, you have to set the request ID to
DIRECT_ACCESS and the update mode to F on the initial screen.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message MCEX260 - DataSource &1: Data access using 'Direct Access' not possible ?

  The SAP error message MCEX260 indicates that there is an issue with accessing a DataSource using "Direct Access." This typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system.
  Cause:
  The error can be caused by several factors, including:
  
  
  DataSource Configuration: The DataSource may not be properly configured for direct access. This could be due to missing settings or incorrect parameters.
  
  
  Source System Issues: The source system (like an SAP ERP system) may not be available, or there may be connectivity issues between the BW system and the source system.
  
  
  Authorization Issues: The user trying to access the DataSource may not have the necessary authorizations to perform the direct access.
  
  
  DataSource Type: The DataSource may not support direct access. Some DataSources are designed for batch processing rather than real-time access.
  
  
  Technical Issues: There could be technical issues such as network problems, system downtime, or other system errors.
  
  
  Solution:
  To resolve the MCEX260 error, you can take the following steps:
  
  
  Check DataSource Configuration:
  
  Go to the DataSource in the SAP BW system and verify its settings.
  Ensure that the DataSource is configured for direct access if it is supposed to support it.
  
  
  
  Verify Source System Connectivity:
  
  Check if the source system is up and running.
  Test the connection from the BW system to the source system using transaction RSA1 (Data Warehousing Workbench) and navigate to the source system settings.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to access the DataSource. This may involve checking roles and profiles assigned to the user.
  
  
  
  Check DataSource Type:
  
  Confirm that the DataSource is indeed designed for direct access. If it is not, consider using a different DataSource or method for data extraction.
  
  
  
  Technical Troubleshooting:
  
  Look into system logs for any errors or warnings that might provide more context about the issue.
  If necessary, consult with your Basis team to check for any underlying system issues.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific DataSource for any known issues or additional configuration steps.
