  1. 
  Cause:
  This warning message occurs when you try to assign or input a value into a one-line element (a field or a node in a structure or internal table) that already contains a value. Essentially, the system is informing you that the field is not empty and already holds some data, so overwriting it might lead to data loss or unintended consequences.
  This often happens in the context of:
  
  Data transfer or data mapping where a field is being filled multiple times.
  When using function modules or BAPIs that expect unique or initial values.
  During data upload or batch input sessions where the same field is updated repeatedly without clearing or resetting it.
