• What is the cause and solution for SAP error message WG105 - Delivery date was forward-scheduled ?

  Certainly! Here's a detailed explanation for the SAP error message WG105 - Delivery date was forward-scheduled:
  
  SAP Error Message: WG105 - Delivery date was forward-scheduled
  Meaning / Cause:
  
  The message WG105 indicates that the requested delivery date in a sales order or delivery document has been forward-scheduled by the system.
  Forward scheduling means that the system could not find availability or capacity to meet the requested delivery date and therefore moved the delivery date to a later date (forward in time).
  This typically happens when the requested delivery date is too early, and the system's availability check or scheduling logic determines that the materials or production capacity are not available until a later date.
  The system informs the user that the delivery date has been adjusted forward to the earliest possible date based on current stock, production, or procurement schedules.
  
  
  When does this occur?
  
  During sales order processing, when the requested delivery date is entered.
  During availability check or scheduling runs.
  When creating or changing delivery documents.
  When the system performs scheduling and finds that the requested date cannot be met.
  
  
  Possible Causes:
  
  Insufficient stock or planned receipts to fulfill the order on the requested date.
  Production or procurement lead times are longer than the requested delivery date allows.
  Capacity constraints in production or shipping.
  Incorrect or overly optimistic requested delivery date entered by the user.
  Scheduling parameters or rules that do not allow backward scheduling or only allow forward scheduling.
  
  
  Solution / How to handle:
  
  
  Review the new delivery date suggested by the system:
  
  Check the forward-scheduled delivery date proposed by SAP.
  Determine if this date is acceptable to the customer or business process.
  
  
  
  Check availability and scheduling details:
  
  Use transaction CO09 (Availability Overview) or MD04 (Stock/Requirements List) to analyze material availability.
  Check planned orders, purchase orders, and stock levels.
  
  
  
  Adjust planning parameters if necessary:
  
  Review and adjust lead times, lot sizes, or scheduling parameters in material master or production master data.
  Check if backward scheduling is possible or allowed in your system settings.
  
  
  
  Communicate with the customer:
  
  Inform the customer about the adjusted delivery date.
  Negotiate if an earlier delivery is critical and explore options like expediting procurement or production.
  
  
  
  Manually adjust the delivery date if justified:
  
  If business allows, manually change the delivery date in the sales order or delivery document.
  Be aware that this may cause availability or capacity conflicts.
  
  
  
  Check for system or master data errors:
  
  Verify that lead times, transit times, and other scheduling parameters are correctly maintained.
  Ensure that the material master data is up to date.
