• What is the cause and solution for SAP error message CNV_PE_CHECK_V2036 - Field &1: Foreign key check field &2 is not compatible ?

  The SAP error message CNV_PE_CHECK_V2036 indicates that there is a foreign key constraint issue in your data migration or conversion process. Specifically, it means that the field specified as &1 is not compatible with the foreign key check field specified as &2. This typically occurs during data migration when the data being imported does not meet the integrity constraints defined in the target database.
  Cause:
  
  Data Type Mismatch: The data type of the field in the source data does not match the data type of the foreign key field in the target table.
  Value Mismatch: The values being imported do not exist in the referenced table, which violates the foreign key constraint.
  Null Values: If the foreign key field does not allow null values, and the source data contains nulls, this will also trigger the error.
  Incorrect Mapping: The mapping of fields between the source and target tables may be incorrect, leading to incompatible data being inserted.
  
  Solution:
  
  Check Data Types: Ensure that the data types of the fields in the source data match those in the target table. If there are discrepancies, you may need to convert the data types in your source data.
  Validate Foreign Key Values: Ensure that all values in the foreign key field in the source data exist in the corresponding primary key field of the referenced table. You may need to clean or adjust your source data accordingly.
  Handle Null Values: If the foreign key field does not allow nulls, ensure that your source data does not contain any null values for that field.
  Review Mapping: Double-check the mapping configuration in your data migration tool to ensure that fields are correctly aligned.
  Use Data Quality Tools: Utilize data quality tools to identify and rectify any inconsistencies in your data before migration.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary) to check the structure of the tables involved and SE16 (Data Browser) to view the data in the tables.
  Foreign Key Constraints: Familiarize yourself with the foreign key constraints defined in the target database to understand the relationships between tables.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  Data Migration Tools: If you are using specific data migration tools (like SAP S/4HANA Migration Cockpit or LSMW), refer to their documentation for best practices and troubleshooting tips.
  
  By addressing the above points, you should be able to resolve the CNV_PE_CHECK_V2036 error and successfully complete your data migration.
