• What is the cause and solution for SAP error message MA102 - Specified period comes before planning start ?

  The SAP error message MA102 ("Specified period comes before planning start") typically occurs in the context of Material Requirements Planning (MRP) or when working with planning data in SAP. This error indicates that the period you are trying to access or process is earlier than the defined planning start date for the material or planning object.
  Cause:
  
  Planning Start Date: The planning start date for the material is set to a date that is later than the period you are trying to work with. This means that the system does not allow you to plan or view data for periods that precede this date.
  Incorrect Date Entry: The user may have inadvertently entered a date that is outside the allowed range.
  Configuration Issues: There may be configuration settings in the MRP or planning parameters that restrict access to certain periods.
  
  Solution:
  
  
  Check Planning Start Date:
  
  Navigate to the material master record (transaction code MM03) and check the MRP views to find the planning start date.

  If you are entering a date manually, ensure that it is within the valid range. Adjust the date to a period that is on or after the planning start date.
