  The SAP error message CNV_MBT_DEX089 Exception EXPORT_NO_SHARED_MEMORY typically occurs during data export processes, particularly in the context of data migration or conversion activities. This error indicates that the system is unable to allocate shared memory for the export operation, which is necessary for handling large datasets.
  Causes:
  
  Insufficient Shared Memory Configuration: The SAP system may not have enough shared memory allocated for the operation. This can happen if the parameters for shared memory are not set correctly in the instance profile.
  System Resource Limitations: The server may be running low on available memory resources, which can prevent the allocation of the required shared memory.
  Configuration Issues: Incorrect configuration settings in the SAP system or the database can lead to this error.

  Monitor System Resources:
