The result of the net calculation simulation cannot 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.

  The SAP error message CRMS4_PS_CONTR018 indicates that there was a failure during the net calculation simulation while building net calculation units in the SAP CRM (Customer Relationship Management) system. This error typically arises in the context of pricing and contract management, particularly when dealing with complex pricing scenarios or conditions.
  Causes:
  
  Missing or Incorrect Data: The error may occur if there are missing or incorrect data entries in the pricing conditions, such as invalid condition records or missing master data (e.g., customer, material).
  Configuration Issues: Incorrect configuration in the pricing procedure or condition types can lead to failures in net calculation.
  Incompatibility with Custom Logic: If there are custom enhancements or user exits that interfere with the standard pricing logic, it may cause the net calculation to fail.
  System Performance Issues: If the system is under heavy load or if there are performance issues, it may lead to timeouts or failures in processing the net calculation.
  Version or Patch Issues: Sometimes, specific versions of SAP may have bugs that can lead to such errors, especially if the system is not up to date with the latest patches.
  
  Solutions:
  
  Check Data Integrity: Verify that all necessary master data (customers, materials, etc.) and pricing conditions are correctly maintained and active.
  Review Pricing Configuration: Ensure that the pricing procedure and condition types are correctly configured. Check for any inconsistencies or missing entries in the configuration.
  Debugging: If you have access to the development environment, you can debug the pricing logic to identify where the failure occurs. Look for any custom code that might be affecting the pricing calculation.
  System Performance: Monitor system performance and check for any bottlenecks. If the system is slow, consider optimizing performance or running the calculation during off-peak hours.
  SAP Notes and Support: Check the SAP Support Portal for any relevant SAP Notes that address this specific error. There may be patches or updates that resolve known issues.
  Consult Documentation: Review the SAP documentation related to pricing and net calculations to ensure that all necessary steps and configurations are followed.
