• What is the cause and solution for SAP error message PMMO_MM_INTEGRATION049 - Recursive level depth cannot be greater than 999 ?

  The SAP error message PMMO_MM_INTEGRATION049, which states "Recursive level depth cannot be greater than 999," typically occurs in the context of Material Management (MM) and Production Planning (PP) integration. This error indicates that a recursive function or process has exceeded the maximum allowed depth of 999 levels, which can happen during operations such as BOM (Bill of Materials) explosion, material master data processing, or during the execution of certain transactions that involve deep hierarchies.
  Causes:
  
  Deep BOM Structure: The most common cause is a Bill of Materials (BOM) that has a very deep hierarchical structure, leading to excessive recursion when the system tries to process it.
  Circular References: There may be circular references in the BOM or routing, causing the system to loop indefinitely until it hits the recursion limit.
  Configuration Issues: Incorrect configuration in the material master or BOM settings can lead to unexpected behavior during processing.
  Custom Code: If there are custom enhancements or user exits that manipulate BOM or material data, they might inadvertently cause deep recursion.
  
  Solutions:
  
  Review BOM Structure: Check the BOM for any unnecessary levels or circular references. Simplifying the BOM structure can help avoid deep recursion.
  Check for Circular References: Ensure that there are no circular references in the BOM or routing. This can be done by reviewing the components and their relationships.
  Limit Depth: If possible, limit the depth of the BOM or the number of levels being processed in a single transaction.
  Debug Custom Code: If there are custom enhancements, debug the code to identify any logic that may be causing excessive recursion.
  SAP Notes: Check for any relevant SAP Notes or patches that may address this issue. SAP frequently releases updates that can resolve known issues.
  Consult Documentation: Review SAP documentation for best practices regarding BOM and material master management to ensure compliance with recommended structures.
  
  Related Information:
  
  Transaction Codes: You may encounter this error during transactions like CS01 (Create BOM), CS02 (Change BOM), or CS03 (Display BOM).
  SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance. They can provide insights based on the specific configuration and data in your system.
  Testing: After making changes, conduct thorough testing to ensure that the changes do not introduce new issues and that the BOM processes correctly.
  
  By addressing the underlying causes and following the suggested solutions, you should be able to resolve the PMMO_MM_INTEGRATION049 error effectively.
