• What is the cause and solution for SAP error message CNV_PE_CHECK_V2029 - Table &1: Foreign key relationship is incomplete ?

  The SAP error message CNV_PE_CHECK_V2029 indicates that there is an issue with a foreign key relationship in a specific table. This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools or during system upgrades.
  Cause:
  The error occurs when:
  
  A foreign key constraint is defined in the database, but the corresponding entries in the referenced table do not exist.
  There are missing or inconsistent data entries that violate the foreign key relationship.
  The data being migrated or converted does not adhere to the integrity constraints defined in the database schema.
  
  Solution:
  To resolve the CNV_PE_CHECK_V2029 error, you can follow these steps:
  
  
  Identify the Table: The error message will specify the table name (denoted as &1). Identify which table is causing the issue.
  
  
  Check Foreign Key Constraints: 
  
  Use transaction code SE11 (Data Dictionary) to check the foreign key relationships for the specified table.
  Identify the foreign key fields and the corresponding primary key fields in the referenced table.
  
  
  
  Validate Data Integrity:
  
  Run SQL queries to check for orphaned records in the table that is causing the error. Look for records that reference non-existent entries in the parent table.
  Example SQL query:
  SELECT * FROM <child_table> WHERE <foreign_key_field> NOT IN (SELECT <primary_key_field> FROM <parent_table>);
  
  
  
  
  Correct Data Issues:
  
  If you find orphaned records, you can either delete them or update them to point to valid entries in the parent table.
