• What is the cause and solution for SAP error message ME402 - Fewer than two schedule lines are not suitable for compression ?

  The SAP error message ME402, which states "Fewer than two schedule lines are not suitable for compression," typically occurs in the context of the Material Management (MM) module when attempting to compress schedule lines in a purchase order or a scheduling agreement. This error indicates that the system requires at least two schedule lines to perform a compression operation, but it has found fewer than that.
  
  Cause:
  
  Insufficient Schedule Lines: The primary cause of this error is that there are not enough schedule lines available for the compression process. Compression is only applicable when there are at least two schedule lines that can be combined into one.
  Single Schedule Line: If there is only one schedule line, the system cannot perform compression, as there is nothing to compress it with.
  Deleted or Inactive Schedule Lines: If schedule lines have been deleted or are inactive, it may lead to fewer than two schedule lines being
