  The SAP error message CNV_MBT_DEX087 typically indicates an import mismatch error that occurs during data migration or data import processes, particularly when using the SAP Data Migration Workbench (DMW) or similar tools. This error is often related to inconsistencies between the data being imported and the target table structure or constraints.
  Cause of the Error:
  
  Data Type Mismatch: The data being imported may not match the expected data types of the target table fields. For example, trying to import a string into a numeric field.
  Field Length Issues: The length of the data being imported may exceed the defined length of the target table fields.
  Missing Required Fields: Required fields in the target table may not be populated in the import data.
  Foreign Key Violations: The data being imported may reference non-existent records in related tables, violating foreign key constraints.
  Incorrect Mapping: The mapping between the source data and the target table may be incorrect, leading to mismatches.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in the target table and ensure that the data being imported matches these types.
  Validate Field Lengths: Ensure that the length of the data being imported does not exceed the maximum length defined for the target fields.
  Populate Required Fields: Make sure that all required fields in the target table are included and populated in the import data.
  Verify Foreign Keys: Check that all foreign key references in the import data correspond to existing records in the related tables.
  Review Mapping Configuration: Double-check the mapping configuration in the data migration tool to ensure that all fields are correctly mapped from the source to the target.
  Use Data Validation Tools: Utilize any available data validation tools or reports in SAP to identify and correct issues in the import data before attempting the import again.
