  The SAP error message /SAPAPO/CIF_NQRFC037 New qRFC API was deactivated on the inbound side typically occurs in the context of the Core Interface (CIF) when there is an issue with the integration between SAP ERP and SAP APO (Advanced Planner and Optimizer). This error indicates that the new qRFC (queued Remote Function Call) API has been deactivated on the inbound side, which can prevent data from being transferred correctly between the systems.
  Cause:
  
  Deactivation of qRFC API: The most common cause of this error is that the new qRFC API has been deactivated in the system settings. This can happen due to configuration changes or updates that have not been properly applied.
  System Configuration Issues: There may be issues with the configuration of the CIF settings, such as incorrect settings in the CIF customizing or missing authorizations.
  Version Compatibility: If there are version mismatches between the SAP ERP and SAP APO systems, it can lead to incompatibility issues with the qRFC API.
  Transport Issues: If there have been recent transports that included changes to the CIF configuration, it may have inadvertently deactivated the qRFC API.
  
  Solution:
  
  Check CIF Settings: Go to the CIF customizing transaction (usually CIF or CIF1) and verify that the qRFC API is activated. You may need to check the settings under the "Integration Model" and ensure that the relevant models are active.
  Activate qRFC API: If the qRFC API is deactivated, you can activate it by navigating to the relevant configuration settings in the CIF customizing and enabling the new qRFC API.
  Review Authorizations: Ensure that the user has the necessary authorizations to execute the qRFC API. This may involve checking roles and profiles assigned to the user.
  Check for Updates: Ensure that both the SAP ERP and SAP APO systems are updated to compatible versions. If there are any patches or updates available, consider applying them.
  Transport Management: If the issue arose after a transport, review the transport logs and settings to ensure that the qRFC API was not inadvertently deactivated during the transport process.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
