• What is the cause and solution for SAP error message WB2B149 - The item category &1 is already defined as default for TC type &2 ?

  The SAP error message WB2B149 indicates that there is a conflict in the configuration of item categories and transaction types in the SAP system. Specifically, it means that the item category you are trying to assign is already set as the default for the specified transaction type.
  Cause:
  This error typically occurs when:
  
  You are attempting to assign an item category to a transaction type that already has a different item category defined as its default.
  There may be a configuration issue where the same item category is being used for multiple transaction types, leading to conflicts.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Configuration:
  
  Go to the configuration settings for the relevant transaction type and item category in the SAP system.
  Use transaction code SPRO to access the SAP Reference IMG.
  Navigate to the relevant path for defining item categories and transaction types (e.g., Sales and Distribution > Sales > Sales Document > Define Item Categories).
  
  
  
  Identify Conflicts:
  
  Look for the transaction type (&2) and see which item category is currently set as the default.
  If the item category (&1) you are trying to assign is already defined as default for another transaction type, you will need to change that configuration.
  
  
  
  Modify Default Settings:
  
  If you need to keep the current default item category for the transaction type, consider changing the default item category for the transaction type you are trying to configure.
  Alternatively, if you want to use the item category you are trying to assign, you may need to remove it as the default for the other transaction type.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs and that the system behaves as expected.
  
  
  
  Related Information:
