How To Fix CK825 - Recursion recognized: Lot size cannot be passed on

SAP Error Message - Details

• Message type: E = Error

• Message class: CK - Product Costing Messages

• Message number: 825

• Message text: Recursion recognized: Lot size cannot be passed on

What causes this issue?

In
<DS:GLOS.3526B726AFAB52B9E10000009B38F974>costing variant</> &V1&, it
was defined that the lot size of the highest material should be
<DS:DE.CK_LOSDR>passed on</>. However, the system found a recursive
structure when exploding the BOM. One of the materials belonging to
this recursion is material &V2& or material &V3& in plant &V4&.

System Response

The system can no longer determine the costing lot sizes dynamically,
and takes them from the costing view in the material master instead.

• What is the cause and solution for SAP error message CK825 - Recursion recognized: Lot size cannot be passed on ?

  The SAP error message CK825, "Recursion recognized: Lot size cannot be passed on," typically occurs in the context of product costing and material management. This error indicates that there is a recursive situation in the costing process, where the system is unable to determine the lot size for a material due to circular references or incorrect configuration.
  Causes:
  
  
  Circular References: The error often arises when there are circular dependencies in the material master data or in the costing variant settings. For example, if a material's lot size is dependent on another material's lot size, which in turn depends back on the first material, it creates a loop.
  
  
  Incorrect Lot Size Configuration: If the lot size settings in the material master or in the costing variant are not configured correctly, it can lead to this error. This includes settings in the material type, valuation class, or other related configurations.
  
  
  Costing Variant Issues: The costing variant may not be set up properly to handle the lot size calculations, leading to recursion.
  
  
  Master Data Issues: Problems with the material master data, such as missing or incorrect entries in the lot size fields, can also trigger this error.
  
  
  Solutions:
  
  
  Check Material Master Data: Review the material master data for the materials involved. Ensure that the lot size settings are correctly defined and that there are no circular dependencies.
  
  
  Review Costing Variant Settings: Check the costing variant settings in the configuration. Ensure that the lot size parameters are set correctly and that there are no conflicting settings.
  
  
  Analyze Dependencies: Use transaction codes like CK11N (Create Cost Estimate with Quantity Structure) to analyze the cost estimate and identify any circular references. Look for any dependencies that may be causing the recursion.
  
  
  Adjust Lot Size Settings: If you find that the lot size settings are incorrect, adjust them accordingly. This may involve changing the lot size type, minimum lot size, or other related parameters.
  
  
  Consult Documentation: Refer to SAP documentation or help notes related to costing and lot size configurations for additional guidance.
  
  
  Testing: After making changes, perform a test run of the costing process to ensure that the error is resolved.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N, CK40N (Change Cost Estimate), and MM02 (Change Material) for managing material master data.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common errors.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, providing insights or solutions from other users' experiences.
