What causes this issue?

You have selected an SAP link method and an additional program name at
the same time or entered a transaction code that is to be executed with
the link. In the SAP link method, documents are only defined or
system-generated program are used. Thus, your entry is not applicable
in this context.

• What is the cause and solution for SAP error message WXP252 - Do not enter a program/transaction for this link method ?

  Certainly! Here's a detailed explanation for the SAP error message WXP252: "Do not enter a program/transaction for this link method":
  
  Error Message:
  WXP252 – Do not enter a program/transaction for this link method
  
  Cause:
  This message occurs in the context of Web Dynpro ABAP applications when defining navigation links between components or component controllers.
  
  In Web Dynpro, when you create a navigation link (used to navigate from one view/component to another), you specify a link method that handles the navigation logic.
  The link method is a method in the Web Dynpro component controller or view controller that is called when the link is triggered.
  WXP252 is raised if you try to assign a program name or transaction code directly to a link method, which is not allowed.
  
  In other words, you cannot assign a program or transaction to a link method because link methods are meant to be ABAP methods that handle navigation internally within the Web Dynpro application, not external programs or transactions.
  
  When does this happen?
  
  When defining navigation links in the Web Dynpro component interface or in the component controller.
  When you mistakenly enter a program name or transaction code in the "Program/Transaction" field for a link method.
  When the link method is expected to be an ABAP method, but the system detects an external program/transaction assignment.
  
  
  Solution:
  
  
  Remove the program/transaction assignment from the link method:
  
  Go to the Web Dynpro component where the navigation link is defined.
  Open the Navigation Links tab.
  Select the link method in question.
  Ensure that the Program/Transaction field is empty for this link method.
  
  
  
  Implement the link method as an ABAP method:
  
  The link method should be implemented in the component controller or view controller.
  This method should contain the logic to perform navigation, e.g., calling wd_this->fire_navigation_out() or similar navigation API calls.
  
  
  
  If you want to call an external program or transaction, do it inside the link method implementation:
  
  Use ABAP statements like CALL TRANSACTION or SUBMIT inside the link method.
  Do not assign the program/transaction directly to the link method in the navigation link definition.
  
  
  
  Use the correct navigation type:
  
  If you want to navigate to another Web Dynpro component, use component usage and navigation links.
  If you want to call an external transaction, handle it programmatically inside the link method.
  
  
  
  
  Additional Information:
  
  
  Web Dynpro Navigation Basics:
  
  Navigation links connect different views or components.
  Link methods are ABAP methods that handle navigation events.
  Navigation is controlled programmatically, not by assigning external programs/transactions directly.
  
  
  
  SAP Note / Documentation:
  
  This error is documented in SAP Web Dynpro ABAP guides.
  SAP recommends handling external calls inside link methods, not by assigning them directly.
  
  
  
  Example:
  
  
  METHOD on_navigation_link.
    " Navigate to another view or component
    wd_this->fire_navigation_out( ).
  
    " Or call an external transaction
    CALL TRANSACTION 'VA01'.
  ENDMETHOD.
  
  Summary:
  
  
  
  Aspect
  Description
  
  
  
  
  Cause
  Program/transaction assigned directly to a Web Dynpro link method, which is not allowed.
  
  
  Solution
  Remove program/transaction from link method assignment; implement navigation logic in method.
  
  
  Related Info
  Navigation links use ABAP methods; external calls must be done inside these methods.
