• What is the cause and solution for SAP error message W8101 - Binding for container types & <- & is not defined ?

  SAP Error Message:
  W8101 Binding for container types & <- & is not defined
  
  Cause
  This warning message occurs in SAP when the system tries to perform a binding operation between two container types (e.g., structures, tables, or other data containers), but no binding definition exists for the specified source and target container types.
  In other words, the system is attempting to map or convert data from one container type to another, but it cannot find a predefined binding rule or method that tells it how to do this.
  This typically happens in scenarios involving:
  
  Data binding in Web Dynpro ABAP components.
  Data transfer between different UI elements or contexts.
  Custom container types or complex data structures without explicit binding definitions.
  Usage of generic binding or conversion functions where the system expects a binding definition.
  
  
  Explanation
  
  The placeholders & <- & in the message represent the source and target container types involved in the binding attempt.
  The system expects a binding definition
