• What is the cause and solution for SAP error message W8158 - Value for container element & is initial, no attributes can be determined ?

  SAP Error Message:
  W8158 Value for container element & is initial, no attributes can be determined
  
  Cause
  This warning message occurs when a container element (usually in an IDoc or XML processing context) has an initial (empty or uninitialized) value. Because the element's value is empty, SAP cannot determine or assign any attributes related to that element.
  In other words, the system expects a value for a particular container element to process or map attributes, but it finds that the element is empty (initial). This often happens during IDoc processing, XML parsing, or when using container elements in function modules or BAPIs that expect filled data.
  
  When does it typically occur?
  
  During IDoc inbound or outbound processing when a segment or field is empty.
  When using container elements in function modules or BAPIs that require non-initial values.
  In XML processing or mapping scenarios where an element is expected to have a value but is empty.
  When data is missing
