SAP S/4HANA Error 548: Invalid Partition Range

📦 SAP S/4HANA

📋

Description

This error indicates a problem with the definition or usage of data partitions within SAP S/4HANA's underlying database or reporting structures. It typically occurs when a system process, report execution, or data management operation attempts to access or create data in a partition range that is incorrectly specified, overlaps, or lies outside the allowed boundaries.

Error Message

ERR_RS_PARTITION_INVALID_RANGE

🔍

Known Causes

3 known causes

⚠️

Incorrect Partition Definition

Partition ranges for a database table or data object are defined incorrectly, leading to overlaps, gaps, or out-of-bounds specifications.

⚠️

Data Load or Query Mismatch

An attempt to load data into a non-existent partition or query data using a range that does not align with the existing partition scheme.

⚠️

System Configuration Desynchronization

The system's internal understanding of partition ranges is out of sync with the actual database structure due to recent changes or failed updates.

Solutions

3 solutions available

1. Verify and Adjust Partition Definitions medium

Correctly define the ranges and boundaries for your table partitions.

Identify the table experiencing the ERR_RS_PARTITION_INVALID_RANGE error. This often happens during data loading or reporting operations.

Access the table's partitioning definition. This can be done via SAP HANA Studio, SAP HANA Cockpit, or SQL commands.

SELECT * FROM SYS.PARTITIONS WHERE TABLE_NAME = '<your_table_name>';

Examine the `RANGE_START` and `RANGE_END` values for each partition. Ensure there are no overlaps or gaps between consecutive partitions. The `RANGE_END` of one partition should be exactly one less than the `RANGE_START` of the next partition (for integer ranges), or the `RANGE_END` of one partition should be the value immediately preceding the `RANGE_START` of the next partition (for date/time ranges).

If overlaps or gaps are found, you will need to alter the table's partitioning. This typically involves dropping and recreating the partitions with corrected definitions. **Caution:** This can be a complex operation and may require downtime. Back up your system before proceeding.

ALTER TABLE <your_table_name> DROP PARTITION <partition_id>;
ALTER TABLE <your_table_name> ADD PARTITION <new_partition_definition>;

Alternatively, if the partitioning is dynamic and managed by SAP BW/4HANA or SAP S/4HANA's data aging, review the data aging object configuration and the rules for partition creation and deletion. Ensure these rules are correctly defined and do not lead to invalid range generation.

2. Rebuild Partitioning Strategy advanced

Recreate the partitioning for a table to resolve persistent range issues.

Identify the problematic table and its current partitioning scheme. It's crucial to understand the data volume and access patterns before proceeding.

Create a temporary table with the same structure as the original table, but without any partitioning.

CREATE TABLE <your_table_name>_TEMP AS SELECT * FROM <your_table_name> WITH NO DATA;

Copy all data from the original partitioned table to the temporary table.

INSERT INTO <your_table_name>_TEMP SELECT * FROM <your_table_name>;

Drop the original partitioned table.

DROP TABLE <your_table_name>;

Recreate the table with the desired partitioning strategy. Ensure the partition definitions are correct and cover the entire expected data range without overlaps or gaps. Consult SAP documentation for best practices on partitioning for your specific S/4HANA version and workload.

CREATE TABLE <your_table_name> (
  <column1> <type1>,
  <column2> <type2>,
  ...
) PARTITION BY RANGE (<partition_column>)
(
  PARTITION <partition_name_1> VALUES LESS THAN (<upper_bound_1>),
  PARTITION <partition_name_2> VALUES LESS THAN (<upper_bound_2>),
  ...
);

Insert the data from the temporary table back into the newly created partitioned table.

INSERT INTO <your_table_name> SELECT * FROM <your_table_name>_TEMP;

Drop the temporary table.

DROP TABLE <your_table_name>_TEMP;

3. Address Data Inconsistencies During Load medium

Ensure data loaded into partitioned tables adheres to partition boundaries.

Identify the data loading process that triggers the error. This could be an ETL job, a direct data import, or an SAP application process.

Review the source data for any values that fall outside the expected range for the partition key column. This might involve data quality checks before loading.

If using SAP Data Services or similar ETL tools, configure the data flow to perform validation on the partition key column before attempting to load data into the target partitioned table.

For custom data loading programs, implement checks within the code to ensure that the values for the partition key column are within the defined ranges of the target partitions. If an invalid value is detected, either reject the record or redirect it to an error handling mechanism.

IF :partition_key_value < :partition_lower_bound OR :partition_key_value >= :partition_upper_bound THEN
  -- Handle error: log, reject, or redirect
ELSE
  -- Proceed with insert into the appropriate partition
END IF;

When loading data using SQL INSERT statements, ensure the `WHERE` clause or the data itself restricts values to valid partition ranges. If you are not explicitly directing data to partitions, the database will attempt to place it based on the defined ranges.

INSERT INTO <your_table_name> (<column1>, <partition_column>, ...) 
SELECT <column1>, <partition_column>, ... 
FROM <source_table> 
WHERE <partition_column> BETWEEN <lower_bound> AND <upper_bound>;
