How To Fix SZDM_CC_CHKS_TITLES121 - An XPRA report uses RFC-calls

SZDM_CC_CHKS_TITLES121 - Overview

• Message type: E = Error

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

• Message number: 121

• Message text: An XPRA report uses RFC-calls

What causes this issue?

A trace in one of the SAP internal test systems has found that your XPRA
report calls a function module via RFC.
The name of the XPRA report 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 XPRA report 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 SLAPI
Search for an entry with name
SAP_XPRA_<name of the XPRA-report> or
<namespace>SAP_XPRA_<name of the XPRA-report>.
If there is no such entry, then create a new one with this name.
For this SLAPI-entry, 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 APIs that is listed in transaction SLAPI,
then enter the name of this APIs in "Ref to other API".
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.

SZDM_CC_CHKS_TITLES121 - Details

• The SAP error message SZDM_CC_CHKS_TITLES121 indicates that an XPRA (eXtended Program Run) report is using RFC (Remote Function Call) calls, which is not allowed in certain contexts. This error typically arises during the execution of an XPRA report that is expected to run in a specific environment or context where RFC calls are restricted.
  
  Cause:
  
  RFC Calls in XPRA: The XPRA report is trying to execute RFC calls, which can lead to issues such as performance degradation or unexpected behavior, especially if the XPRA is designed to run in a background process or during system upgrades.
  System Configuration: The system may be configured to disallow RFC calls during certain operations, such as during the execution of XPRA reports, to maintain data integrity and consistency.
  
  
  Solution:
  
  Review the XPRA Code: Check the code of the XPRA report to identify where the RFC calls are being made. If possible, modify the code to eliminate the RFC calls
