SAP S/4HANA Error 365: No Primary Key Match

📦 SAP S/4HANA

📋

Description

This error indicates that a database operation, such as an insert or update, failed because a foreign key value in the current record does not correspond to an existing unique or primary key in the referenced table. It typically occurs when referential integrity is violated, preventing the system from maintaining data consistency.

💬

Error Message

ERR_SQL_NO_MATCHING_UNIQUE_OR_PRIMARY_KEY

🔍

Known Causes

4 known causes

⚠️

Missing Master Data

A foreign key in the transactional data points to a primary key that does not exist in the corresponding master data table.

⚠️

Data Migration/Integration Issues

Data loaded into SAP S/4HANA did not correctly establish or validate all required referential integrity links.

⚠️

Custom Development Errors

Custom ABAP code or SQL statements attempt to create or modify records without ensuring the existence of related primary key entries.

⚠️

Inconsistent Data Updates

A parent record with a primary key was inadvertently deleted or modified, leaving child records with invalid foreign key references.

Solutions

3 solutions available

1. Verify Data Integrity of Primary Key Fields medium

Ensures that the data in the primary key fields of the involved tables is consistent and adheres to uniqueness constraints.

Identify the tables and fields involved in the transaction that triggered error 365. This often requires analyzing the SAP application logs (SM21) or the ST05 SQL trace.

Connect to the S/4HANA database using a SQL client (e.g., SAP HANA Studio, DBeaver, or the `hdbsql` command-line tool).

For each identified table, run a query to check for duplicate primary key values. Replace `<table>` and `<pk_field1>`, `<pk_field2>`, etc. with the actual table and primary key column names.

SELECT <pk_field1>, <pk_field2>, COUNT(*) FROM <table> GROUP BY <pk_field1>, <pk_field2> HAVING COUNT(*) > 1;

If duplicate primary keys are found, investigate the cause. This might involve incorrect data loading, faulty custom code, or application bugs. Correct the duplicate entries by either deleting the redundant rows or updating them to be unique.

DELETE FROM <table> WHERE <pk_field1> = 'duplicate_value' AND <pk_field2> = 'another_duplicate_value' AND ROWID != (SELECT MIN(ROWID) FROM <table> WHERE <pk_field1> = 'duplicate_value' AND <pk_field2> = 'another_duplicate_value');

Also, check for NULL values in primary key fields, as primary keys are not allowed to be NULL. Replace `<pk_field>` with the primary key column name.

SELECT COUNT(*) FROM <table> WHERE <pk_field> IS NULL;

If NULL values are found, identify the cause and correct the data. This might involve updating the rows with appropriate values.

UPDATE <table> SET <pk_field> = 'appropriate_value' WHERE <pk_field> IS NULL AND <other_conditions_to_identify_row>;

2. Analyze and Correct Application Logic advanced

Addresses potential issues in the SAP application code that might be attempting to insert or update records with non-unique primary keys.

Consult the SAP application logs (SM21) and the ST05 SQL trace during the execution of the problematic transaction. Look for the specific SQL statement that failed with error 365.

Identify the SAP transaction code (T-code) or program that is executing the failing statement.

Using SAP ABAP Debugger (SE80, SE38), set breakpoints in the relevant ABAP code that generates the SQL statement. Step through the code to understand how the primary key values are being determined.

Check for scenarios where the application might be attempting to create a new record with an existing primary key, or update a record using a non-existent primary key. This could be due to incorrect logic in data retrieval, sequence generation, or user input validation.

Modify the ABAP code to ensure that primary key values are unique before attempting to insert or update records. This might involve using SAP's standard mechanisms for generating unique keys (e.g., sequences) or implementing robust validation checks.

Example ABAP logic (conceptual):

IF sy-tcode = 'MY_TCODE'.
  DATA: lv_pk_value TYPE ztable-pk_field.
  CALL FUNCTION 'MY_SEQUENCE_GENERATOR' IMPORTING ev_value = lv_pk_value.
  IF lv_pk_value IS INITIAL.
    MESSAGE 'Error generating primary key' TYPE 'E'.
  ENDIF.
  " Use lv_pk_value for INSERT/UPDATE
ENDIF.

Test the corrected ABAP code thoroughly in a development or quality assurance environment before deploying to production.

3. Review and Correct Database Constraints medium

Ensures that the primary key constraints in the database are correctly defined and enforced.

Connect to the S/4HANA database using a SQL client.

Query the system views to examine the primary key constraints for the relevant tables. Replace `<table>` with the table name.

SELECT CONSTRAINT_NAME, TABLE_NAME, COLUMN_NAME, POSITION FROM CONSTRAINTS WHERE TABLE_NAME = '<table>' AND CONSTRAINT_TYPE = 'PRIMARY KEY' ORDER BY CONSTRAINT_NAME, POSITION;

Verify that the primary key is correctly defined with the expected columns and order. If the constraint is missing or incorrectly defined, it needs to be corrected.

If the primary key constraint is missing, you can add it. **Caution:** This should only be done after verifying data integrity to avoid creating duplicates. Replace `<table>`, `<pk_field1>`, `<pk_field2>`, and `<constraint_name>`.

ALTER TABLE <table> ADD CONSTRAINT <constraint_name> PRIMARY KEY (<pk_field1>, <pk_field2>);

If the constraint is incorrect, it might need to be dropped and recreated. **Caution:** This will temporarily disable the constraint and should be done during a maintenance window with extreme care. Replace `<constraint_name>` and `<table>`.

ALTER TABLE <table> DROP CONSTRAINT <constraint_name>;

After dropping, recreate the correct primary key constraint using the syntax from step 4.
