SAP S/4HANA Error 5424: Unsupported Filter Request
Description
This error indicates that the system received a filter criterion that it cannot process or does not support for the current operation. It typically occurs when users attempt to apply complex, custom, or syntactically incorrect filters during data retrieval, reporting, or API interactions within SAP S/4HANA.
Error Message
ERR_TEXT_FCA_UNSUPPORTED_FILTER
Known Causes
3 known causesInvalid Filter Syntax or Parameter
The filter applied contains incorrect syntax, a misspelled field name, or an unsupported parameter for the specific data object or report.
Unsupported Filter Type for Context
A filter type (e.g., a specific operator or function) is used on a field or in a context where it is not logically or technically supported by SAP S/4HANA.
Custom Development/API Mismatch
In custom applications or API integrations, a filter is being passed that the underlying SAP S/4HANA service or CDS view does not expose or support.
Solutions
3 solutions available1. Review and Simplify OData Filter Expressions medium
Adjust OData service calls to use supported filter functions and operators.
1
Identify the OData service and the specific filter expression causing the error. This often requires debugging the frontend application or tracing OData requests.
2
Consult the SAP Gateway service documentation (available via transaction `/IWFND/MAINT_SERVICE`) for the specific OData service. Look for the 'Service Implementation' tab and then the 'Filter' or 'Supported Query Options' section to understand which filter functions and operators are allowed.
3
Modify the OData request to remove or replace unsupported filter functions (e.g., complex string manipulations within filters, unsupported date functions) or operators. For instance, if `endswith` is not supported, you might need to fetch a broader dataset and filter it on the client-side or redesign the OData service to support the required functionality.
Example of a potentially problematic filter: `$filter=substringof('abc', MyStringField) and MyDateField gt datetime'2023-01-01T00:00:00Z'`
Example of a simplified filter (if supported): `$filter=MyStringField eq 'abc*'` or `$filter=MyDateField gt 2023-01-01`4
If the business logic absolutely requires complex filtering that is not supported by the standard OData service, consider extending the OData service using SAP Gateway tools (e.g., SEGW) to implement custom logic or expose new, more specific query options.
2. Check and Update SAP Gateway (OData) Service Implementation advanced
Ensure the backend OData service implementation correctly handles filter requests and supports the used operators.
1
Access the SAP Gateway service builder (transaction `SEGW`).
2
Locate the OData service that is generating the error.
3
Review the service implementation, particularly the `GET_ENTITYSET` method for the relevant entity. Examine how filter parameters are processed. Ensure that the underlying ABAP code correctly interprets and applies the filter conditions to the data retrieval logic.
Within the `GET_ENTITYSET` method, look for code that parses `$filter` query options and translates them into WHERE clauses for ABAP data retrieval (e.g., using `cl_http_utility=>unescape_url` and `cl_gw_filter_parser`). Ensure all supported filter operators are handled.4
If using standard SAP Fiori applications, check for available annotations and annotations that might influence filtering. Ensure these are correctly configured and activated.
5
If custom logic is involved, verify that the filtering logic does not use unsupported SQL constructs or inefficient data retrieval methods that might indirectly lead to this error in the OData layer.
3. Verify Data Type Compatibility in Filters medium
Ensure that the data types used in the filter expression match the underlying data types of the fields being filtered.
1
Identify the fields used in the problematic OData filter expression.
2
Determine the exact data types of these fields in the SAP S/4HANA database (e.g., using transaction `SE11` to inspect the table definition).
3
Compare these data types with the format of the values provided in the filter. For example, filtering a `DATS` (date) field with a string that is not in the expected `YYYYMMDD` format or an `INT4` field with a non-numeric string will cause issues.
Example: If `MyDateField` is a `DATS` type, the filter value should be a date string, not a timestamp or a plain string. `$filter=MyDateField eq '20230101'` is likely correct, while `$filter=MyDateField eq '01/01/2023'` or `$filter=MyDateField eq 20230101` might be incorrect depending on the OData service's parsing capabilities.4
Adjust the filter values to match the expected data type format. This might involve client-side formatting before sending the OData request.
