SAP S/4HANA Error 549: Invalid Partition Type Encountered
Description
This error indicates that an attempt was made to create or modify a data partition within SAP S/4HANA using an unsupported or incorrectly specified partition type. It typically occurs during data modeling, system configuration, or data migration activities when defining how data should be organized and stored in the underlying database.
Error Message
ERR_RS_PARTITION_INVALID_TYPE
Known Causes
3 known causesIncorrect Partition Type Definition
The specified partition type in the data model or configuration does not conform to the allowed types for the specific database object or SAP S/4HANA version.
Mismatched Database Capability
The chosen partition type is not supported by the underlying database system (e.g., SAP HANA) or its current configuration for the target table or object.
Typographical Error in Configuration
A simple spelling mistake or incorrect syntax was used when defining the partition type in configuration files, scripts, or user interfaces.
Solutions
3 solutions available1. Verify and Correct Partition Definition in SAP HANA Table medium
Re-examine the table definition and ensure the partition type is valid for SAP HANA.
1
Identify the table experiencing the error. This often requires reviewing the SAP application logs or tracing the error back to a specific database operation.
2
Connect to the SAP HANA database using a tool like SAP HANA Studio or hdbsql.
3
Query the system views to retrieve the table's partitioning information. Replace 'YOUR_TABLE_NAME' with the actual table name.
SELECT PARTITION_NAME, PARTITION_TYPE FROM SYS.TABLE_PARTITIONS WHERE TABLE_NAME = 'YOUR_TABLE_NAME';4
Review the `PARTITION_TYPE` column for any invalid or unsupported types. Common valid types include 'RANGE', 'HASH', 'ROUNDROBIN'. If an invalid type is found, you will need to redefine the partition.
5
If the partition type is invalid, you will need to drop and recreate the table with the correct partitioning. This is a significant operation and should be performed during a maintenance window with proper backups.
DROP TABLE YOUR_TABLE_NAME;
-- Recreate table with valid partitioning, for example:
CREATE COLUMN TABLE YOUR_TABLE_NAME (
-- column definitions...
) PARTITION BY RANGE (YOUR_PARTITION_COLUMN) (
PARTITION p1 VALUES LESS THAN ('2023-01-01'),
PARTITION p2 VALUES LESS THAN ('2024-01-01')
);2. Check for SAP Note Corrections for Partitioning Issues medium
Apply relevant SAP Notes that address known bugs or inconsistencies in SAP HANA partitioning.
1
Access the SAP Support Portal (SAP ONE Support Launchpad).
2
Navigate to the 'SAP Notes & KBA' search section.
3
Search for SAP Notes related to 'SAP HANA partitioning', 'ERR_RS_PARTITION_INVALID_TYPE', or 'Error 549'. Include your SAP HANA version in the search.
4
Carefully review the search results for any notes that match your observed error and SAP HANA version. Pay attention to the 'Symptom' and 'Solution' sections.
5
If a relevant SAP Note is found, follow the provided instructions for applying the correction. This may involve downloading and applying a support package or manually implementing changes.
6
After applying any SAP Notes, restart the SAP HANA system or relevant services as instructed and retest the operation that caused the error.
3. Investigate Custom Table Creation Scripts or Data Loading Tools medium
Review the source of the table creation or modification to identify potential errors in partition definition.
1
Identify the process or tool used to create or modify the table that is causing the error. This could be a custom SQL script, an ETL tool, or a data migration utility.
2
Obtain the script or configuration file used for the table creation/modification.
3
Carefully examine the `PARTITION BY` clause within the script or configuration. Verify that the specified partition type (e.g., RANGE, HASH) is correctly spelled and is a supported type in your SAP HANA version.
4
Check for any typos, incorrect syntax, or unsupported partition key definitions. For example, ensure the partition column is of a compatible data type for the chosen partitioning method.
5
If an error is found, correct the script or configuration and re-execute the process to recreate or modify the table with the valid partitioning.
6
If the issue arises from an ETL tool or data loading utility, consult its documentation for correct partitioning syntax and ensure it aligns with SAP HANA's requirements.
