Description

This error indicates that an API call to SAP S/4HANA contained a statement or request that was syntactically incorrect or improperly formed. It typically occurs when an external system or custom application attempts to interact with SAP S/4HANA APIs using an invalid format or command.

Error Message

ERR_API_INV_STATEMENT: Invalid statement

🔍

Known Causes

4 known causes

⚠️

Incorrect API Call Syntax

The API request sent to SAP S/4HANA contains syntax errors, such as misspelled commands, incorrect parameter names, or improper formatting.

⚠️

Missing Required Parameters

Essential parameters or fields required for the API statement to be valid were omitted from the request.

⚠️

Data Type Mismatch

The data provided in the API request does not match the expected data type for a specific parameter, leading to an invalid statement.

⚠️

API Version Incompatibility

The API statement used is incompatible with the version of the SAP S/4HANA API being called, often due to deprecated features or new requirements.

Solutions

3 solutions available

1. Review and Correct API Statement Syntax easy

The most common cause is a syntactical error in the API call.

1

Identify the specific API call that is failing. This is usually logged in the SAP system's transaction logs (e.g., SM21, ST22) or the calling application's logs.

2

Carefully examine the syntax of the API statement. Look for common errors such as:

- Missing or extra commas
- Incorrectly quoted strings
- Mismatched parentheses or brackets
- Typographical errors in keywords or parameter names
- Incorrect data types for parameters
- Invalid characters

3

Refer to the official SAP API documentation for the specific API you are using to ensure correct syntax and parameter usage. SAP's API documentation is typically found in the SAP Help Portal or within the SAP system itself (e.g., through transaction SE37 for BAPIs).

4

Correct any identified syntax errors in the API statement.

5

Re-test the API call to verify the error is resolved.

2. Validate API Parameters and Data Types medium

Incorrect parameter values or data types can lead to invalid API statements.

1

Pinpoint the API statement causing the ERR_API_INV_STATEMENT error.

2

Consult the API's documentation to understand the expected parameters, their data types, and any constraints (e.g., mandatory fields, value ranges).

3

Verify that all parameters being passed to the API are of the correct data type. For example, if a parameter expects an integer, ensure a string is not being passed.

Example: If an API expects a numeric customer ID, ensure '12345' is passed, not 'ABCDE' or '12345 ' (with a space).

4

Check that the values provided for each parameter are valid according to the API's business logic and any predefined value lists or formats.

Example: If a country code parameter expects a 2-character ISO code, ensure 'US' is passed, not 'United States' or 'USA'.

5

If the API is called from custom code (e.g., ABAP, external application), review the code that prepares and passes these parameters.

6

Adjust parameter values or data types in the calling code to match the API's requirements.

7

Retest the API call after making corrections.

3. Check API Authorization and Access medium

Ensuring the user or system calling the API has the necessary authorizations.

1

Identify the user ID or system user that is executing the API call. This can often be found in the error logs.

2

In SAP S/4HANA, use transaction `PFCG` to check the roles assigned to this user. Examine the authorization objects within these roles.

3

If the API is a BAPI or RFC-enabled function module, specific authorizations are required. Common authorization objects include `S_RFC` (for RFC access) and specific authorization objects related to the business object the API interacts with (e.g., `S_TABU_DIS` for table access, or specific authorization objects for sales orders, materials, etc.).

4

If the API is part of a newer SAP S/4HANA service (e.g., OData service), check the relevant authorization objects for that service. This might involve checking `S_SERVICE` for service activation and potentially other authorization objects defined for the service's underlying business logic.

5

If the necessary authorizations are missing, work with your SAP security administrator to grant them. Ensure the user has the correct `ACTVT` (activity) and `OBJECT` values for the relevant authorization objects.

6

After authorizations are updated, log out and log back into the SAP system (or restart the calling application) for the changes to take effect.

7

Re-test the API call.
