  SAP Error Message: WXP649
  Text:
  
  Assign an "allocation table" interface to the layout
  
  Cause
  This error occurs in SAPscript or Smart Forms when you try to use an interface in a layout (form) that requires an allocation table interface but none has been assigned. In other words, the layout expects an interface that provides an allocation table (a special kind of interface used to allocate data dynamically), but the form or the interface assignment is missing or incorrect.
  This typically happens when:
  
  You have defined a layout that requires an allocation table interface, but you have not assigned the interface to the layout.
  The interface assigned to the layout does not contain the necessary allocation table.
  You are trying to use a layout that expects a certain interface type, but the interface is missing or incorrectly linked.
  
  
  Solution
  To resolve the error WXP649, you need to:
  
  
  Assign the correct allocation table interface to the layout:
  
  Go to the Form Painter or Smart Forms transaction where the layout is defined.
  Check the interface assigned to the layout.
  Make sure that the interface assigned contains the allocation table (an internal table or structure that the layout expects).
  If the interface is missing or incorrect, assign the correct interface that includes the allocation table.
  
  
  
  Check the interface definition:
  
  Use transaction SE80 or SE37 to check the interface or function module interface.
  Verify that the interface contains the required allocation table parameters.
  
  
  
  Adjust the layout or interface if necessary:
  
  If the layout does not require an allocation table, remove the requirement or adjust the layout accordingly.
  If the interface does not have the allocation table, add it or create a new interface that includes it.
  
  
  
  Re-activate the form/layout after changes.
