How To Fix BGRFC461 - Destination &1 does not have enough resources for a unit size of &2 bytes

SAP Error Message - Details

• Message type: E = Error

• Message class: BGRFC - qRFC - New Background RFC

• Message number: 461

• Message text: Destination &1 does not have enough resources for a unit size of &2 bytes

What causes this issue?

The destination system does not currently have sufficient resources
available to execute the units. This could be a temporary bottleneck.
Repeat the health check again later.

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

System Response

How to fix this error?

If the problem persists, start transaction SARFC in the destination
system to perform a more precise analysis.

• What is the cause and solution for SAP error message BGRFC461 - Destination &1 does not have enough resources for a unit size of &2 bytes ?

  The SAP error message BGRFC461 indicates that the destination specified in the error does not have enough resources to handle a unit size of the specified number of bytes. This typically occurs in the context of background RFC (Remote Function Call) processing, where the system is trying to send data to a remote system or process, but the destination is unable to accommodate the request due to resource limitations.
  Cause:
  
  Insufficient Memory: The destination system may not have enough memory allocated to handle the incoming request.
  Configuration Issues: The configuration settings for the destination may not be optimized for the size of the data being sent.
  Network Issues: There may be network constraints that limit the amount of data that can be processed at once.
  System Load: The destination system may be under heavy load, causing it to reject additional requests or data.
  
  Solution:
  
  
  Increase Resources: 
  
  Check the memory and resource allocation on the destination system. If possible, increase the available resources (e.g., memory, CPU).
  
  
  
  Adjust Configuration:
  
  Review the configuration settings for the RFC destination in transaction SM59. Ensure that the settings are appropriate for the expected data size.
  You may need to adjust the Max Data Size parameter for the RFC destination.
  
  
  
  Batch Processing:
  
  If the data being sent is too large, consider breaking it into smaller batches. This can help the destination system process the data more effectively.
  
  
  
  Monitor System Load:
  
  Check the performance and load on the destination system. If it is under heavy load, consider scheduling the data transfer during off-peak hours.
  
  
  
  Check Network Configuration:
  
  Ensure that there are no network limitations that could be affecting the data transfer. This includes checking firewalls, routers, and any other network devices that may impose limits.
  
  
  
  Review Logs:
  
  Check the logs on both the sending and receiving systems for any additional error messages or warnings that could provide more context about the issue.
