  Error Message
  WXP602: Assign an interface for promotions to layout &3
  
  Cause
  This message occurs in SAP when you are working with promotion layouts in the SAP IS-Retail or SAP Promotion Management module, specifically in the context of promotion pricing or promotion condition layouts.
  The system expects that a promotion interface (a program or function module that processes promotion data) is assigned to the promotion layout you are trying to use. If no interface is assigned, the system cannot process the promotion correctly, and this error is raised.
  In other words, the layout you are trying to use for promotions does not have an interface assigned to it, which is mandatory for the system to know how to handle the promotion data.
  
  When does it occur?
  
  When creating or changing promotion layouts.
  When executing promotion pricing or promotion condition processing.
  When the system tries to process a promotion but cannot find the interface linked to the layout.
  
  
  Solution
  To resolve this error, you need to assign a promotion interface to the promotion layout. This is done in the configuration or customizing of promotion layouts.
  Steps to assign an interface to a promotion layout:
  
  
  Go to the SAP Customizing Implementation Guide (IMG):
  
  Transaction code: SPRO
  
  Path:
  
  SAP Reference IMG ?
  
  Retail ?
  
  Promotion Management ?
  
  Promotion Layouts ?
  
  Define Promotion Layouts
  
  
  Select the promotion layout (&3 refers to the layout name or ID in the error message).
  
  
  Assign the appropriate interface:  
  
  The interface is usually a function module or a program that processes the promotion data.  
  Choose the interface that matches your promotion type or business requirement.
  
  
  
  Save your changes.
  
  
  Test the promotion processing again.
  
  
  
  Additional Information
  
  The interface defines how the promotion data is processed and displayed. Without it, the system cannot interpret the promotion layout.
  If you are unsure which interface to assign, consult your functional consultant or check the documentation for your specific promotion type.
  Sometimes, custom interfaces are created for specific business needs; ensure the correct custom interface is assigned if applicable.
  This error is common during initial setup or when new promotion layouts are created but not fully configured.
