How To Fix WXCM011 - No function module is stored for attribute & in Customizing

SAP Error Message - Details

• Message type: E = Error

• Message class: WXCM - Messages for Package CM_MAP

• Message number: 011

• Message text: No function module is stored for attribute & in Customizing

What causes this issue?

You want to construct attribute &V1&. Attributes are either supplied
with a dummy value, or constructed using a function module. The
attribute assignment (and context structure) for the relevant function
module is defined in a customizing table (TWISPC_FBATTRB).
However, in the customizing table for attribute &V1&, no function
module is stored that defines the characteristic values, independently
of a context structure.

System Response

The system could not create the master data hierarchy.

How to fix this error?

Specify a dummy value for the attribute, or create in Customizing, an
entry for the attribute that contains the function module for
constructing the attribute (without context structure). You do this in
transaction CMMAP04.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WXCM011 - No function module is stored for attribute & in Customizing ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WXCM011 No function module is stored for attribute & in Customizing
  
  Cause:
  This error occurs when the SAP system tries to process a Web Dynpro or CRM Web UI component that requires a function module linked to a specific attribute, but no function module has been assigned or maintained for that attribute in the Customizing settings.
  In other words, the system expects a function module to be configured for a particular attribute (the placeholder & in the message is replaced by the actual attribute name at runtime), but it cannot find any entry in the customizing tables.
  This typically happens in CRM Web UI or Web Dynpro applications where attribute-specific logic is implemented via function modules, and the configuration is incomplete or missing.
  
  Where does this happen?
  
  In SAP CRM Web UI or Web Dynpro applications.
  When attribute-specific processing is required (e.g., for attribute determination, validation, or enhancement).
  During runtime when the system tries to call the function module linked to an attribute.
  
  
  Solution:
  
  
  Identify the Attribute:
  
  Check the exact attribute name in the error message (the & will be replaced by the attribute name).
  Note down the attribute for which the function module is missing.
  
  
  
  Maintain the Function Module in Customizing:
  
  Go to the relevant customizing transaction or IMG path where function modules are assigned to attributes.
  For CRM Web UI, this is often under:
  SPRO -> Customer Relationship Management -> UI Framework -> Generic Interaction Layer -> Attribute Determination -> Assign Function Module to Attribute
  
  Or use transaction SM30 to maintain the table that stores attribute-function module assignments (e.g., CRMC_UI_ATTR_FM or similar).
  
  
  
  Assign/Create the Function Module:
  
  If a standard function module exists for the attribute, assign it.
  If not, you may need to create a custom function module that implements the required logic for the attribute.
  Ensure the function module follows the expected interface and behavior.
  
  
  
  Transport the Changes:
  
  After maintaining the customizing, transport the changes to the relevant systems (DEV ? QA ? PROD).
  
  
  
  Test the Application:
  
  Re-run the scenario to verify that the error no longer occurs.
  
  
  
  
  Additional Information:
  
  Function Module Role: The function module linked to an attribute typically handles dynamic value determination, validation, or other attribute-specific logic.
  Debugging: You can debug the Web Dynpro or CRM Web UI component to see where the function module call is triggered.
  SAP Notes: Check SAP Notes for any known issues related to this error message and your SAP version.
  Customizing Tables: The exact customizing table or IMG path may vary depending on the SAP CRM or Web Dynpro version.

  Error
  WXCM011 No function module is stored for attribute & in Customizing
  
  
  Cause
  Missing function module assignment for an attribute in customizing
  
  
  Solution
  Maintain the function module assignment for the attribute in customizing (SPRO or SM30)
  
  
  Context
  CRM Web UI, Web Dynpro, attribute-specific processing
  
  
  Additional
  Create custom FM if needed, test after changes
  
  
  
  
  If you provide the exact attribute name or the context (e.g., which application or transaction), I can help you with more precise customizing paths or function module examples.
