  The SAP error message CNV_PE_CHECK_V2090 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.

  Incorrect Configuration: The migration or conversion configuration may have been set up incorrectly, leading to multiple source tables being defined for a single operation.
  Data Mapping Issues: The mapping of source data to target structures may not be properly defined, causing the system to interpret multiple sources.
  Custom Code or Enhancements: If there are custom enhancements or modifications in the migration process, they may inadvertently introduce multiple source tables.

  Review Configuration: Check the configuration settings for the migration or conversion process. Ensure that only one source table is defined for the operation in question.
