Message type: E = Error
Message class: FDT_CORE - Formula & Derivation Tool: Core
Message number: 148
Message text: No valid interface, &1 does not exist
The signature of an BRFplus expression type is defined by an ABAP-OO
interface. The functionality is defined in an ABAP-OO class implementing
that interface. This class also needs to implement the interface
IF_FDT_EXPRESSION.
Optionally there can be further classes defined for an expression type.
These are a query class, a UI class and a data exchange class. For a
detailed description of the functionality provided by these classes,
refer to the BRFplus documentation. If one of the classes is set it
needs to implement a corresponding interface.
These are the following:
The query class needs to implement IF_FDT_OBJECT_QUERY
The UI class needs to implement IF_FDT_UI_DEFINITION
The data exchange class needs to implement IF_FDT_DATA_EXCHANGE_EXTERNAL
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
Specify a correct interface and correct classes for the expression type.

FDT_CORE148
- No valid interface, &1 does not exist ?The SAP error message FDT_CORE148: No valid interface, &1 does not exist typically occurs in the context of SAP Forms and Document Management, particularly when working with Adobe Forms or other form-related functionalities. This error indicates that the system is unable to find a valid interface for the specified object or form.
Cause:
Missing Interface: The specified interface (denoted by
&1
in the error message) does not exist in the system. This could be due to a number of reasons, such as:
- The interface was never created.
- The interface was deleted or not properly activated.
- There is a typo in the interface name or it is incorrectly referenced in the form.
Transport Issues: If the interface was transported from another system, there may have been issues during the transport process that caused the interface not to be available.
Authorization Issues: The user may not have the necessary authorizations to access the interface.
Configuration Issues: There may be configuration issues in the form or the associated settings that prevent the interface from being recognized.
Solution:
Check Interface Existence:
- Go to transaction SE80 (Object Navigator) or SE37 (Function Module) and check if the interface exists.
- If it does not exist, you may need to create it or restore it from a backup.
Correct References:
- Ensure that the form or document is correctly referencing the interface. Check for any typos or incorrect naming conventions.
Transport Validation:
- If the interface was supposed to be transported, check the transport logs for any errors. Ensure that the transport request was successfully imported into the target system.
Authorization Check:
- Verify that the user has the necessary authorizations to access the interface. You may need to consult with your security team to ensure proper roles and permissions are assigned.
Re-activate the Interface:
- If the interface exists but is not active, try reactivating it. Sometimes, reactivation can resolve issues related to inconsistencies.
Check Configuration:
- Review the configuration settings related to the form and interface. Ensure that all necessary settings are correctly configured.
