How To Fix SZDM_CC_CHKS_TITLES120 - An After Import Method uses RFC-calls

SAP Error Message - Details

• Message type: E = Error

• Message class: SZDM_CC_CHKS_TITLES - Title messages related to check classes

• Message number: 120

• Message text: An After Import Method uses RFC-calls

What causes this issue?

A trace in one of the SAP internal test systems has found that your
after-import-method (AIM) calls a function module via RFC.
The name of the AIM and the name of the system where the trace was
executed and where you can find the call stack leading to the RFC call
can be found in the detailed messages.

System Response

If the AIM runs as part of a zero-downtime-upgrade in a customer system,
then the upgrade procedure aborts with an error message. Solving this
kind of errors requires help from the SAP development support.

How to fix this error?

If the RFC function module runs in the same system as the caller, then
you must make sure that you have declared all database tables the RFC
module reads from or writes to.
If you have already declared all these tables then apply for an
exemption for this ATC-message.
If you have not yet declared the tables, then make the necessary
declarations in your development or maintenance system:
Call transaction SOBJ_EXT.
Enter the name of the transport object type that triggers the AIM.
Select "Used database tables" in the navigation area.
Enter the names of the accessed tables with an appropriate value for
"Access type" and "Lock mode".
If the RFC module calls an API that is listed in transaction SLAPI, then
enter the name of this API in "Used APIs".
If the RFC module calls an API that is not listed in transaction SLAPI
<(>,<)> then ask the owner of the API to create an SLAPI entry for this
API and declare all accessed tables there.

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 SZDM_CC_CHKS_TITLES120 - An After Import Method uses RFC-calls ?

  The SAP error message SZDM_CC_CHKS_TITLES120 indicates that there is an issue with an After Import Method that is using Remote Function Call (RFC) calls. This typically occurs during the import of transport requests in SAP, particularly when the system detects that the After Import Method is trying to execute RFC calls, which is not allowed in certain contexts.
  Cause:
  
  RFC Calls in After Import Method: The After Import Method is designed to perform actions after a transport request has been imported. However, using RFC calls in this method can lead to issues, as it may attempt to access remote systems or perform actions that are not permitted during the import process.
  System Configuration: The system may be configured to restrict certain operations during the import process to ensure data integrity and consistency.
  Custom Code: If there is custom code in the After Import Method that includes RFC calls, this could trigger the error.
  
  Solution:
  
  Review the After Import Method: Check the implementation of the After Import Method in the transport request. Look for any RFC calls and remove or modify them to avoid using RFC during the import process.
  Use Local Functionality: If the functionality that requires the RFC call can be achieved using local function modules or methods, consider refactoring the code to use those instead.
  Testing: After making changes, test the transport request in a development or quality assurance environment to ensure that the error is resolved and that the After Import Method works as intended without RFC calls.
  Documentation: Refer to SAP documentation or notes related to transport management and After Import Methods for best practices and guidelines.
  
  Related Information:
  
  Transport Management System (TMS): Understanding how TMS works in SAP can provide insights into the restrictions and best practices for transport requests.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling After Import Methods.
  Debugging: If you have access to debugging tools, you can set breakpoints in the After Import Method to analyze the flow and identify where the RFC calls are being made.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with an SAP Basis expert for further assistance.
