The SAP error message CNV_CDMC_CC017 typically indicates that a requested action in the SAP system may take a long time to complete. This message is often associated with data conversion or migration processes, particularly in the context of the SAP Conversion and Migration (CDMC) tools.
Cause: Long-Running Processes: The action you are trying to perform is resource-intensive and may require significant processing time. This can happen during data migration, conversion, or large batch processing tasks. System Performance: The performance of the SAP system may be affected by various factors, such as high system load, insufficient resources (CPU, memory, disk I/O), or network latency. Data Volume: The volume of data being processed can also contribute to the time it takes to complete the action. Large datasets will naturally take longer to process.
