• What is the cause and solution for SAP error message WG353 - Max.coverage is &3 days for material &1, plant &2, iteration &4 days ?

  The SAP error message:
  WG353 Max.coverage is &3 days for material &1, plant &2, iteration &4 days
  typically occurs in the context of SAP's Repetitive Manufacturing (REM) or Production Planning (PP) processes, especially during the calculation of production quantities or coverage periods.
  
  Meaning of the Message
  
  
  Message Text:
  
  "Max.coverage is &3 days for material &1, plant &2, iteration &4 days"
  
  
  Variables:  
  
  &1 = Material number  
  &2 = Plant  
  &3 = Maximum allowed coverage period (in days)  
  &4 = Current iteration coverage period (in days)
  
  
  
  This message indicates that during the planning or calculation run, the system has detected that the coverage period (the time span for which demand is covered by planned production) for the specified material and plant has exceeded the maximum allowed coverage period.
  
  Cause
  
  The coverage period (the time horizon for which demand is planned to be covered) calculated in the current iteration (&4 days) exceeds the maximum allowed coverage period (&3 days) set in the system.
  This usually happens during the repetitive manufacturing planning run or demand coverage calculation when the system tries to plan production for a period longer than what is configured as acceptable.
  The maximum coverage period is a control parameter to avoid planning too far into the future, which could lead to inaccurate or inefficient production plans.
  
  
  Where is this parameter maintained?
  
  The maximum coverage period is typically maintained in the repetitive manufacturing parameters or planning parameters for the material or plant.
  It can be set in customizing under:
  
  SPRO -> Production -> Repetitive Manufacturing -> Planning -> Define Maximum Coverage Period
  
  
  Solution
  
  
  Check and adjust the maximum coverage period:
  
  Go to the customizing path mentioned above.
  Review the maximum coverage period set for the material and plant.
  If the business process requires a longer coverage period, increase the maximum coverage period accordingly.
  
  
  
  Review the demand and planning horizon:
  
  Check if the demand or forecast data is causing the system to plan too far ahead.
  Adjust the demand or forecast horizon if necessary.
  
  
  
  Check the planning run parameters:
  
  Sometimes, the planning run or the repetitive manufacturing planning run parameters specify a coverage period.
  Adjust these parameters to align with the maximum coverage period.
  
  
  
  Review the material master and planning data:
  
  Check if the material master data (MRP type, lot size, planning horizon) is set correctly.
  Incorrect settings can cause the system to plan beyond the allowed coverage.
  
  
  
  
  Additional Information
  
  This message is informational but indicates a planning inconsistency that should be addressed to ensure efficient production planning.
  Ignoring this message may lead to production plans that are not realistic or that cover too long a period, causing inventory or capacity issues.
  If you are unsure about changing the maximum coverage period, consult with your production planning or SAP PP consultant.
  
  
  Summary
  
  
  
  Aspect
  Details

  Coverage period in planning exceeds max allowed
  
  
  Effect
  Planning run stops or warns about coverage limit
  
  
  Solution
  Increase max coverage period or adjust planning parameters
  
  
  Customization
