System Response

The result of the net calculation simulation could not be determined.

How to fix this error?

Additional messages should allow you to find out the reason of the
failure. If required, contact your system administrator for support.
Net calculation simulation is organized in the following steps:
Mapping of the selection criteria to net calculation units
Net calculation units are the data format used for net calculation
execution and queries.
Gross entitlement and gross payment determination
If required, the entered or changed SSP or SDP data is handled by gross
entitlement and gross payment determination. As a result, a gross
payment document (GPD) is created but not stored in the database. The
GPD is handed over to the next processing step.
Net calculation execution (simulation only)
If a new GPD is available, the net calculation is processed for it.
Query of result
A query is executed to provide the net calculation result for the
entered selection criteria. The data is fetched from the database but
the net calculation result of the prior step is included, if it exists.
If no entered or changed SSP or SDP data is provided, the result of the
net calculation simulation displays the database content. This is the
net calculation result that reflects the current status regarding the
billing process.

Procedure for System Administrators

• What is the cause and solution for SAP error message PSSC_CONTR020 - Net calculation simulation failed while querying result ?

  The SAP error message PSSC_CONTR020 indicates that there was a failure during the net calculation simulation while querying the results in the SAP system. This error typically occurs in the context of SAP Convergent Charging (SAP CC) or similar modules where net calculations are performed.
  Possible Causes:
  
  Configuration Issues: Incorrect configuration settings in the charging or pricing models can lead to simulation failures.
  Data Integrity Problems: Missing or inconsistent data in the relevant tables can cause the simulation to fail.
  Performance Issues: If the system is under heavy load or if there are performance bottlenecks, it may lead to timeouts or failures in processing.
  Version Compatibility: If there are discrepancies between different versions of SAP components, it may lead to unexpected errors.
  Custom Code Issues: If there are custom enhancements or modifications in the system, they may interfere with the standard processing logic.
  
  Solutions:
  
  Check Configuration: Review the configuration settings for the charging models and ensure that all necessary parameters are correctly set.
  Data Validation: Verify the integrity of the data being used in the simulation. Check for missing or incorrect entries in the relevant master data and transactional data.
  System Performance: Monitor system performance and check for any resource bottlenecks. If necessary, optimize the system or schedule simulations during off-peak hours.
  Review Logs: Check the application logs and system logs for any additional error messages or warnings that could provide more context about the failure.
  Test in Development: If possible, replicate the issue in a development or test environment to isolate the cause without affecting production data.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of the software you are using for any known issues or patches.
  Contact SAP Support: If the issue persists, consider reaching out to SAP support for assistance, providing them with detailed information about the error and the context in which it occurred.
  
  Related Information:
  
  SAP Notes: Search for relevant SAP Notes that may address this specific error or provide guidance on troubleshooting.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed.
  Documentation: Review the official SAP documentation for the module in question to understand the expected behavior and configuration requirements.
  
  By following these steps, you should be able to identify the root cause of the error and implement a suitable solution.
