  • What is the cause and solution for SAP error message WD416 - Container element '&' is not multiline ?
    SAP Error Message:
    WD416 Container element '&' is not multiline
    
    Cause
    This error occurs in Web Dynpro ABAP when you try to assign or bind a multiline string (text with line breaks) to a container element that is defined as a single-line element. In other words, the container element (context attribute or UI element) is not designed to hold multiline text, but the data you are trying to put into it contains line breaks or multiple lines.
    For example, if you have a context attribute or UI element of type string (which is single-line) and you try to assign a text with newline characters (\n or CL_ABAP_CHAR_UTILITIES=>NEWLINE), the framework raises this error.
    
    Explanation
    
    Container element: This is typically a context attribute or UI element in Web Dynpro.
    Not multiline: The element is defined as a single-line string.
    '&': The placeholder in the error message is replaced by the name of the container element causing the issue.
    
    
    Solution
