  The SAP error message MPD104: Cycle set has not been maintained; enter cycle set data typically occurs in the context of production planning and control, particularly when working with Master Production Scheduling (MPS) or Material Requirements Planning (MRP). This error indicates that the system is unable to find a defined cycle set for the material or production process you are trying to work with.
  Cause:

  To resolve the MPD104 error, you can follow these steps:
  
  
  Define Cycle Set:
  
  Go to the transaction code MD61 (for MPS) or MD02 (for MRP) depending on your context.

  Create or maintain the cycle set by entering the necessary data such as cycle frequency, duration, and any other relevant parameters.
  
  
  
  Check Material Master:
  
  Ensure that the material master data is complete and correctly configured. You can check this using transaction code MM03.
