• What is the cause and solution for SAP error message WG343 - Please position cursor in a header line ?

  SAP Error Message: WG343 – "Please position cursor in a header line"
  
  Cause:
  The error message WG343 typically occurs in SAP when you attempt to perform an action that requires the cursor to be positioned on a header line in a document or list, but the cursor is currently not on a header line. This is common in SAP modules like SAP WM (Warehouse Management) or SAP LE (Logistics Execution), especially when working with transfer orders, delivery documents, or warehouse tasks.
  For example, in a transfer order processing screen, certain functions (like confirming, changing, or deleting) require the user to select or place the cursor on a header line (which represents the overall document or order header), rather than on an item or detail line.
  
  Solution:
  
  Position the cursor on a header line: Before executing the function or action, make sure to click or navigate so that the cursor is on the header line of the document or list.
  Check the screen layout: Identify which lines are header lines (usually they are visually distinct or grouped) and select one of those lines.
  Use the correct selection method: Sometimes, you need to select the entire line or use a checkbox next to the header line.
  Review the transaction or program documentation: Some transactions require explicit selection of header lines for certain operations.
  
  
  Related Information:
  
  This message is a standard SAP message related to user interface navigation and selection.
  It is often encountered in warehouse management transactions such as:
  
  LT12 (Confirm Transfer Order)
  LT21 (Display Transfer Order)
  LT22 (Change Transfer Order)
  
  
  The message ensures that users do not accidentally perform header-level operations on item-level data.
  If you are developing or customizing SAP screens or reports, ensure that the logic checks for cursor position or selection on header lines before proceeding with header-level operations.
  If the message appears unexpectedly, verify that the screen or ALV grid is functioning correctly and that the user is aware of the required selection.
  
  
  Summary:
  
  Cause: Cursor not positioned on a header line when required.
  Solution: Place the cursor on a header line before executing the action.
  Context: Common in warehouse management and logistics transactions involving document headers.
