WD346 - Details

• The SAP error message WD346: "Rule & cannot be used for this function" typically occurs in the context of Web Dynpro ABAP development. Here's a detailed explanation of the cause, solution, and related information:
  
  Cause
  
  Context: The error arises when a rule (such as a context mapping rule, value mapping rule, or any other Web Dynpro rule) is used in a place or function where it is not allowed or supported.
  Specific Reason: The rule you are trying to apply is either incompatible with the function or method you are using it in, or the rule is not designed to be used in that particular context.
  For example, you might be trying to use a context mapping rule in a place where only a value mapping rule is allowed, or vice versa.
  Another common cause is that the rule is not properly defined or activated, or the function expects a different type of input.
