What causes this issue?

In the case of a sub-day replenishment lead time, a shift sequence is
necessary.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Enter a kanban calculation profile with a shift sequence for the demand
source (consumer) or supply source in the control cycle or specify a

• What is the cause and solution for SAP error message PK566 - Shift sequence necessary in case of sub-day replenishment lead time ?

  The SAP error message PK566, which states "Shift sequence necessary in case of sub-day replenishment lead time," typically occurs in the context of production planning and inventory management within SAP. This error is related to the planning of replenishment processes, particularly when dealing with sub-day lead times for materials.
  Cause:
  The error arises when the system requires a shift sequence to be defined for materials that have a replenishment lead time that is less than one day (sub-day). This situation can occur in environments where materials need to be replenished frequently and in small quantities, such as in just-in-time (JIT) manufacturing or in environments with high turnover rates.
  Solution:
  To resolve the PK566 error, you need to ensure that a shift sequence is defined for the relevant materials. Here are the steps to do this:
  
  
  Define Shift Sequence:
  
  Go to the transaction code OOSB (Define Shift Sequence).
  Create or modify a shift sequence that corresponds to your operational requirements. Ensure that it includes the necessary shifts and timings.
  
  
  
  Assign Shift Sequence to Material:
  
  Navigate to the material master data using transaction code MM02 (Change Material).
  In the relevant views (usually the MRP or Work Scheduling view), assign the newly created shift sequence to the material.
  
  
  
  Check Replenishment Lead Time:
  
  Ensure that the replenishment lead time for the material is correctly set. If it is indeed sub-day, confirm that the shift sequence aligns with your operational schedule.
  
  
  
  Re-run Planning:
  
  After making the necessary adjustments, re-run the planning process (e.g., MRP run) to see if the error persists.
  
  
  
  Related Information:
  
  Shift Sequences: Shift sequences are used in SAP to define the working hours and shifts of a production facility. They are crucial for scheduling and planning purposes, especially when dealing with production orders and material requirements.
  Replenishment Lead Time: This is the time required to replenish stock, which can include procurement, production, and transportation times. Sub-day lead times indicate that replenishment needs to occur within a 24-hour period, often necessitating more precise scheduling.
  Transaction Codes:
  
  MM02: Change Material Master
  OOSB: Define Shift Sequence
  MD01: MRP Run
  
  
  
  By following these steps and ensuring that the shift sequence is properly defined and assigned, you should be able to resolve the PK566 error and continue with your planning processes in SAP.
