• What is the cause and solution for SAP error message COM_PRODUCT_BOM101 - Item number &1 already contained in overview ?

  The SAP error message COM_PRODUCT_BOM101 indicates that an item number is already present in the Bill of Materials (BOM) overview. This typically occurs when you attempt to add an item to a BOM that is already included in that BOM.
  Cause:
  
  Duplicate Entry: The most common cause is that the item you are trying to add is already listed in the BOM.
  Incorrect Data Entry: There may have been a mistake in data entry, leading to an attempt to add the same item multiple times.
  System Configuration: In some cases, system settings or configurations may allow for duplicate entries, but the error is triggered due to validation rules.
  
  Solution:
  
  Check BOM Overview: Review the BOM overview to confirm whether the item is already included. You can do this by navigating to the BOM transaction (e.g., CS03 for display) and checking the item list.
  Remove Duplicate: If the item is indeed listed, you do not need to add it again. If you need to change the quantity or other details, you can edit the existing entry instead.
  Correct Data Entry: If you believe the item should not be in the BOM, verify the item number and ensure you are working with the correct BOM.
  Use Different Item: If you need to add a different item, ensure that you are using the correct item number that is not already in the BOM.
  Consult Documentation: If you are unsure about the BOM structure or how to manage items, refer to SAP documentation or your organization's guidelines on BOM management.
  
  Related Information:
  
  BOM Transactions: Familiarize yourself with relevant BOM transactions in SAP, such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM).
  SAP Notes: Check for any SAP Notes related to BOM management that might provide additional insights or solutions for specific scenarios.
  User Permissions: Ensure that you have the necessary permissions to modify BOMs, as restrictions may lead to unexpected errors.

  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant for further assistance.
