• What is the cause and solution for SAP error message LD038 - Line segment selected has already been defined as a feeder line ?

  The SAP error message LD038, which states "Line segment selected has already been defined as a feeder line," typically occurs in the context of the Logistics Execution (LE) module, particularly when dealing with line items in delivery documents or shipment processing.

  Cause:

  Check Line Segment Definition: Review the line segments in the delivery or shipment document to ensure that the line segment you are trying to define is not already marked as a feeder line. You can do this by navigating to the relevant document and checking the line item details.
  Remove Duplicate Definition: If you find that the line segment is indeed marked as a feeder line, you will need to either remove the feeder line designation or choose a different line segment that is not already defined as a feeder line.
  Review Configuration: If the issue persists, it may be necessary to review the configuration settings related to line segments and feeder lines in the SAP system. This may involve consulting with your SAP Basis or configuration team to ensure that the settings are correct.
