How To Fix RT198 - Minimum number of calls with status CPICERR

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 198

• Message text: Minimum number of calls with status CPICERR

What causes this issue?

Here, you see the number of tRFC calls which could not be carried out
because of a problem contacting or communicating with the destination
system or external component. Such calls are optionally re-scheduled as
background processing jobs and are retried. Whether these calls are
retried and how many times they should be retried is specified for each
RFC destination in transaction SM59. By default, retry of calls is in
use.
You see here only tRFC calls with communication errors. Outbound qRFC
calls, which can also have this status, are not monitored directly.
Rather, the alert monitor watches over the status of the queues to which
qRFC calls belong.
You can display communication errors with the ARFCSSTATE monitor
(analysis method). You will also find detailed information in the ALE
monitoring tree on CPIC error calls that were generated by ALE.

System Response

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

How to fix this error?

Normally, you should see few or no calls with communication problems.
However, communication problems do not necessarily represent a problem.
For example, CPI-C errors may occur if a server or system is down for
maintenance. If the destination is returned to service before the retry
interval runs out, then the tRFC calls are automatically processed.
For this reason, alerts because of accumulations of CPI-C errors
initially carry the alert criticality yellow.
If the CPI-C errors are not caused by a routine and self-correcting
problem such as servicing, then you must check the network connection to
the destination server or component. In addition to actual network
problems, CPI-C errors may be caused by:
an inactive Gateway process in the calling or destination system
an incorrect CPI-C implementation in an external server
incorrect data in the definition of the destination in the calling
system (transaction SM59).
You can test connections to RFC destinations in transaction SM59.
After you have corrected the problem, affected calls are automatically
processed if the retry interval has not elapsed.
Otherwise, you can trigger processing an affected LUW by hand in
transaction SM58 (the analysis method for tRFC).
Once successfully processed, calls with communication errors are
automatically deleted from the tRFC work queue and will no longer appear
in this monitor.

• What is the cause and solution for SAP error message RT198 - Minimum number of calls with status CPICERR ?

  The SAP error message RT198, which indicates "Minimum number of calls with status CPICERR," typically relates to issues in the communication between SAP systems or between an SAP system and an external system. This error is often associated with the Common Programming Interface for Communication (CPIC), which is used for communication between SAP systems and other applications.
  Cause:
  
  Network Issues: There may be network connectivity problems between the SAP system and the database or between different SAP systems.
  Configuration Errors: Incorrect configuration settings in the SAP system or in the communication parameters can lead to this error.
  Resource Limitations: The system may be running out of resources (e.g., memory, CPU) which can affect communication.
  Database Issues: Problems with the database, such as locks or performance issues, can also lead to CPIC errors.
  Authorization Issues: The user or service account may not have the necessary permissions to perform the required operations.
  
  Solution:
  
  Check Network Connectivity: Ensure that there are no network issues between the systems. You can use tools like ping or traceroute to diagnose connectivity problems.
  Review Configuration Settings: Verify the configuration settings in the SAP system, especially those related to communication and connection parameters. Check the RFC destinations and ensure they are correctly configured.
  Monitor System Resources: Use transaction codes like SM50 or SM66 to monitor system performance and check for any resource bottlenecks.
  Database Health Check: Check the database for locks, performance issues, or any other anomalies. You may need to consult your database administrator for this.
  Check Authorizations: Ensure that the user or service account has the necessary authorizations to perform the required actions. You can use transaction SU53 to analyze authorization issues.
  Review Logs: Check the system logs (transaction SM21) and the developer traces (transaction ST22) for any additional error messages that might provide more context about the issue.
  
  Related Information:
  
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with transaction codes like SM21 (System Log), ST22 (Dump Analysis), SM50 (Process Overview), and SM66 (Global Process Overview) for monitoring and troubleshooting.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  
  If the problem persists after trying the above solutions, it may be necessary to escalate the issue to SAP support for further assistance.
