  The SAP error message PK591 ("Enter either planning calendar or factory calendar") typically occurs in the context of production planning or material requirements planning (MRP) when the system requires a calendar to be specified for planning purposes. This error indicates that neither a planning calendar nor a factory calendar has been defined for the relevant planning object, such as a material or a production order.
  Cause:
  
  Missing Calendar Assignment: The planning object (e.g., material, production order) does not have a planning calendar or factory calendar assigned.
  Configuration Issues: The configuration settings in the system may not have been set up correctly, leading to the absence of a calendar.
  Data Entry Error: During the creation or modification of a planning object, the user may have overlooked entering the required calendar information.
  
  Solution:
  
  
  Assign a Planning Calendar:
  
  Navigate to the relevant material or production order in the SAP system.
  Check the planning view and ensure that either a planning calendar or a factory calendar is assigned.
  If not, assign the appropriate calendar.
  
  
  
  Check Configuration:
  
  Go to the configuration settings in SAP (transaction code SPRO).
  Ensure that the planning and factory calendars are defined correctly in the system.
  Verify that the calendars are linked to the relevant plants and materials.
  
  
  
  Use Transaction Codes:
  
  Use transaction codes like MM02 (Change Material) to update the material master data and assign the necessary calendar.
  For production orders, use CO02 (Change Production Order) to check and assign the calendar.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to planning calendars and factory calendars for additional guidance on how to set them up correctly.
  
  
  
  User Training:

  Related Information:

  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP Run), MD02 (MRP for Single Material), and MD04 (Stock/Requirements List) for planning activities.
