JIT call</> or a control cycle of the category <LS>automatic summarized
JIT call</> already exists which references an IM stock which is already
accessed by other control cycles.

System Response

If you create the control cycle, the system can then no longer execute
any automatic supply-to-production for the control cycle, category
<LS>automatic supply-to-production</> as the stock is no longer uniquely
assigned to this control cycle.

How to fix this error?

You can only avoid this problem by using a

• What is the cause and solution for SAP error message PK487 - Several control cycles refer to the stock in storage location &1 ?

  The SAP error message PK487 indicates that there are multiple control cycles that reference the stock in a specific storage location. This typically occurs in the context of Production Planning (PP) and Material Requirements Planning (MRP) when there are conflicting control cycles for the same stock.
  Cause:
  The error arises when:
  
  Multiple Control Cycles: More than one control cycle is defined for the same storage location and material. Control cycles are used in the MRP process to manage the planning of materials and production.
  Configuration Issues: There may be a misconfiguration in the control cycle settings, leading to overlaps or conflicts.
  Data Integrity Issues: There could be inconsistencies in the master data related to the materials or storage locations.
  
  Solution:
  To resolve the PK487 error, you can take the following steps:
  
  
  Identify Control Cycles:
  
  Use transaction code PK05 (Display Control Cycle) to check the control cycles defined for the material in the specified storage location.
  Identify all control cycles that reference the same storage location.
  
  
  
  Review and Modify Control Cycles:
  
  Determine if all control cycles are necessary. If not, consider deleting or modifying the redundant control cycles.
  Ensure that each control cycle is uniquely defined for the materials and storage locations involved.
  
  
  
  Check Master Data:
  
  Review the material master data and storage location settings to ensure there are no inconsistencies.
  Make sure that the control cycle settings align with the overall production and inventory management strategy.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed guidance on managing control cycles and MRP settings.
  
  
  
  Testing:
  
  After making changes, test the MRP run again to ensure that the error is resolved and that the planning process works as expected.
  
  
  
  Related Information:
  
  Control Cycle: A control cycle in SAP is a mechanism that defines how materials are planned and managed in production. It includes parameters such as the planning strategy, lot size, and safety stock levels.
  MRP (Material Requirements Planning): MRP is a production planning, scheduling, and inventory control system used to manage manufacturing processes.
  Transaction Codes:
  
  PK05: Display Control Cycle
  PK01: Create Control Cycle
  PK02: Change Control Cycle
