SAP S/4HANA Error 669: SQL Spatial Data Processing Issue
Description
Error 669, identified as ERR_SQL_SPATIAL_ERROR, indicates a problem during the processing of spatial or geographical data within SAP S/4HANA. This typically occurs when the system attempts to execute database operations involving location-based information, geometry, or mapping functions.
Error Message
ERR_SQL_SPATIAL_ERROR
Known Causes
4 known causesInvalid Spatial Data Format
This occurs when spatial data provided to a database function or application is not in an expected or valid format, such as incorrect coordinates, geometry types, or projection systems.
Incorrect Database Configuration
The underlying database (e.g., SAP HANA) or its spatial extensions may not be correctly configured or initialized to handle spatial data operations as required by the application.
Spatial Data Corruption
Existing spatial data within the database might be corrupt, incomplete, or malformed, causing errors when applications attempt to read, process, or update it.
Missing Spatial Indexes
Performance-critical spatial queries might fail or encounter errors if required spatial indexes are missing, incorrectly defined, or not optimized on relevant tables.
Solutions
3 solutions available1. Verify Spatial Data Type and SRID Configuration medium
Ensures spatial data is correctly defined and referenced within the database.
1
Identify the SAP S/4HANA tables and columns involved in the spatial operation that is triggering error 669. This might require consulting SAP notes or debugging the application logic.
2
Connect to the SAP HANA database using a suitable client (e.g., SAP HANA Studio, DBVISUAL).
3
Query the metadata to verify the spatial data type (e.g., ST_POINT, ST_GEOMETRY) and the Spatial Reference Identifier (SRID) of the columns. Ensure they are consistent with the expected spatial data.
SELECT TABLE_NAME, COLUMN_NAME, DATA_TYPE, SRID FROM "SYS"."TABLE_COLUMNS" WHERE SCHEMA_NAME = '<your_schema>' AND DATA_TYPE LIKE 'ST_%';4
If the SRID is incorrect or missing, you may need to re-create or alter the table with the correct SRID. This is a more involved process and might require data migration. Consult SAP documentation for best practices on altering spatial data types and SRIDs in S/4HANA.
5
Ensure that the spatial functions being used in the application or queries are compatible with the defined data types and SRIDs. For example, if you are performing a spatial join, ensure both tables have compatible SRIDs or that transformations are handled correctly.
2. Analyze and Re-index Spatial Indexes medium
Optimizes spatial query performance by ensuring spatial indexes are valid and efficient.
1
Identify the spatial indexes associated with the tables involved in the error. You can list spatial indexes using the following query:
SELECT INDEX_NAME, TABLE_NAME, COLUMN_NAME, INDEX_TYPE FROM "SYS"."INDEXES" WHERE SCHEMA_NAME = '<your_schema>' AND INDEX_TYPE = 'SPATIAL';2
Check the status and validity of these spatial indexes. In SAP HANA, spatial indexes are typically managed automatically, but issues can arise. Rebuilding or re-organizing the index might resolve the issue.
3
If performance is a concern or if there's suspicion of index corruption, consider rebuilding the spatial index. This might involve dropping and recreating the index or using specific HANA maintenance tools. **Caution:** Rebuilding indexes can lock tables and impact performance during the operation. Plan this during a maintenance window.
ALTER TABLE <your_schema>.<your_table> DROP PRIMARY STATS;
-- Then, depending on the HANA version and specific index type, you might need to re-create it or HANA might automatically rebuild it on subsequent operations. Consult SAP HANA Spatial documentation for precise commands.4
If the error persists, consider analyzing the query plan for the spatial operations. Use `EXPLAIN PLAN FOR <your_spatial_query>` to identify potential bottlenecks or inefficient index usage.
EXPLAIN PLAN FOR SELECT ... FROM <your_table> WHERE ST_Intersects(<spatial_column>, ST_GeomFromWkt('<your_wkt_geometry>')) = 1;3. Review SAP Notes and Apply Patches easy
Addresses known bugs and issues related to SAP S/4HANA spatial processing.
1
Search the SAP Support Portal (SAP ONE Support Launchpad) for SAP Notes related to 'SAP S/4HANA', 'SQL Spatial Data Processing Issue', 'ERR_SQL_SPATIAL_ERROR', and the specific SAP HANA version you are running.
2
Pay close attention to notes that mention specific spatial functions, data types, or scenarios that match your error. Look for recommendations on configuration, parameter settings, or required patches.
3
If a relevant SAP Note is found, follow its instructions precisely. This might involve applying a Support Package, a specific patch, or making configuration changes.
4
Ensure your SAP S/4HANA system and underlying SAP HANA database are up-to-date with the latest relevant Support Packages and patches. Outdated versions can contain known bugs that have been resolved in newer releases.
