• What is the cause and solution for SAP error message CL481 - Choose either "compressed" or "uncompressed" explosion ?

  The SAP error message CL481, which states "Choose either 'compressed' or 'uncompressed' explosion," typically occurs in the context of the SAP Production Planning (PP) module, particularly when dealing with bill of materials (BOM) and routing explosions in the context of production orders or planning.
  Cause:
  This error arises when the system is unable to determine the type of explosion to perform on a BOM. In SAP, there are two types of explosions:
  
  Compressed Explosion: This type of explosion summarizes the components and sub-components in a more condensed format, which is useful for high-level overviews.
  Uncompressed Explosion: This type provides a detailed breakdown of all components and sub-components, showing the entire hierarchy.
  
  The error occurs when the system expects a selection between these two options but does not receive a clear directive from the user or the configuration.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration: Ensure that the configuration settings for the BOM explosion are correctly set up in the system. This can be done in the following way:
  
  Go to the transaction code SPRO (SAP Reference IMG).
  Navigate to Production -> Basic Data -> Material Master -> BOM -> Define BOM Explosion.
  Check the settings for the explosion type and ensure that the system is configured to allow for either compressed or uncompressed explosions.
  
  
  
  User Input: If the error is occurring during a specific transaction (like creating a production order), ensure that the user is prompted to select either a compressed or uncompressed explosion. This may involve modifying the user interface or the transaction variant to include this selection.
  
  
  Transaction Settings: If you are using a specific transaction (like CO01 for production orders), check the settings in that transaction to ensure that the explosion type is being correctly specified.
  
  
  Debugging: If the issue persists, consider debugging the transaction to see where the selection is failing. This may require assistance from a technical consultant or developer.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error. Sometimes, there are known issues or patches that can resolve such problems.
  
  
  Consult Documentation: Review the SAP documentation for the specific module you are working with to ensure that you are following the correct procedures for BOM explosion.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CO01 (Create Production Order).
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  Training: Consider additional training on SAP PP and BOM management to better understand the functionalities and configurations.
  
  By following these steps, you should be able to resolve the CL481 error and successfully perform the desired BOM explosion in SAP.
