SAP Error Message - Details

• Message type: E = Error

• Message class: RSCRT - Near-To-Real-Time Messages

• Message number: 348

• Message text: Cannot assign daemon &2 to data transfer process &1

What causes this issue?

You are trying to assign data transfer process (DTP) &V1& to DataSource
&V3&. DataSource &V3& is assigned to daemon &V2&. All DTPs that transfer
data to InfoProvider &V4& and the DataSources of these DTPs must be
assigned to the same daemon. A different daemon is assigned to at least
one other DTP and to its DataSource.

System Response

You cannot assign data transfer process &V1& to DataSource &V3& .

How to fix this error?

Do one of the following:
Use only one of the data transfer processes for real-time data
acquisition.
Assign the same daemon to the data transfer process and to its
DataSources. For technical reasons, multiple data transfer processes
cannot transfer data to the same DataStore object at the same time.

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 RSCRT348 - Cannot assign daemon &2 to data transfer process &1 ?

  The SAP error message RSCRT348 indicates that there is an issue with assigning a daemon to a data transfer process (DTP). This error typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there are problems with the configuration or availability of the background processes that handle data transfers.
  Cause:
  
  Daemon Unavailability: The specified daemon (background process) is not available or not running. This could be due to system configuration issues or the daemon process being stopped.
  Configuration Issues: There may be misconfigurations in the settings for the data transfer process or the associated daemons.
  Resource Limitations: The system may be running out of resources (e.g., memory, CPU) to allocate to the daemon.
  Network Issues: If the daemon is supposed to run on a different server, network connectivity issues could prevent it from being assigned.
  
  Solution:
  
  Check Daemon Status: Verify that the daemon processes are running. You can do this by checking the transaction codes like SM50 or SM66 to see if the relevant background processes are active.
  Restart Daemons: If the daemon is not running, restart it. This can often resolve temporary issues.
  Review Configuration: Check the configuration settings for the data transfer process and ensure that they are correctly set up. This includes checking the settings in the Data Warehousing Workbench.
  System Resources: Monitor system resources to ensure that there are enough available for the daemons to operate. If necessary, optimize resource allocation or increase system capacity.
  Check Logs: Review the system logs (transaction SM21) for any additional error messages or warnings that could provide more context about the issue.
  Network Configuration: If the daemon is on a different server, ensure that there are no network issues preventing communication between the servers.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 (to check background jobs), RSCAT (to manage data transfer processes), and RSCONN01 (to check connection settings).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide patches and updates that could resolve underlying issues.
  Documentation: Review SAP documentation related to data transfer processes and daemon management for best practices and troubleshooting steps.
