• What is the cause and solution for SAP error message /SCWM/LK026 - Receiving and transmitting systems must be entered ?

  The SAP error message /SCWM/LK026 indicates that the receiving and transmitting systems must be specified in the context of a logistics execution process, particularly in the SAP Extended Warehouse Management (EWM) module. This error typically arises when there is an attempt to process a document (like a transfer order or delivery) without the necessary configuration for the receiving and transmitting systems.
  Cause:
  
  Missing Configuration: The receiving and transmitting systems are not defined in the system settings. This can happen if the necessary configuration for the integration between systems (like SAP EWM and SAP ERP) has not been completed.
  Incorrect Document Type: The document type being processed may not have the required settings for the receiving and transmitting systems.
  Master Data Issues: The master data for the relevant materials, storage locations, or other entities may not be properly maintained, leading to the absence of necessary system information.

  Check Configuration:

  Review Document Type Settings:
