• What is the cause and solution for SAP error message BOM_S4000 - Material and Usage are mandatory inputs ?

  The SAP error message BOM_S4000, which states "Material and Usage are mandatory inputs," typically occurs when you are trying to create or modify a Bill of Materials (BOM) in SAP without providing the required fields for material and usage. This error is common in the BOM creation process, particularly in the context of the SAP ERP system.
  Cause:
  
  Missing Material Number: The material number is not provided or is incorrect. The system requires a valid material number to associate the BOM with a specific material.
  Missing Usage: The usage field, which indicates the application or context in which the BOM is used (e.g., production, engineering, etc.), is not filled in. This field is essential for the system to understand how the BOM will be utilized.
  Incorrect Transaction: You may be using a transaction that does not support BOM creation or modification without these mandatory fields.
  
  Solution:
  To resolve the BOM_S4000 error, follow these steps:
  
  
  Check Material Number:
  
  Ensure that you have entered a valid material number in the BOM creation or modification screen.
  If you are unsure about the material number, you can use transaction code MM03 to check the material master data.
  
  
  
  Specify Usage:
  
  Make sure to fill in the usage field. Common usage values include:
  
  1: Production
  2: Engineering
  3: Sales
  
  
  The usage field is typically a dropdown or input field in the BOM creation screen.
  
  
  
  Review Transaction Code:
  
  Ensure you are using the correct transaction code for creating or modifying a BOM (e.g., CS01 for creating a BOM, CS02 for changing a BOM).
  If you are using a custom transaction or program, verify that it is designed to handle BOM entries correctly.
  
  
  
  Check User Authorizations:
  
  Ensure that you have the necessary authorizations to create or modify BOMs in the system.
  
  
  
  Consult Documentation:
  
  If you are still facing issues, refer to SAP documentation or consult with your SAP support team for further assistance.

  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level) and their specific requirements.
  Transaction Codes: Familiarize yourself with relevant transaction codes for BOM management:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to BOM management that might be relevant to your version of SAP.
