  The SAP error message 29571, "Superior bill of material must be an order BOM," typically occurs when there is an attempt to create or modify a bill of materials (BOM) in a way that does not comply with the requirements for a superior BOM in the context of production orders.
  Cause:
  This error usually arises in the following scenarios:
  
  Incorrect BOM Type: The superior BOM you are trying to reference is not defined as an "Order BOM" (BOM type 1 or 2 in SAP). An Order BOM is specifically designed for production orders and is different from a standard BOM.
  BOM Hierarchy Issues: If you are trying to create a multi-level BOM and the superior BOM is not set up correctly as an order BOM, this error will occur.
  Configuration Issues: There may be configuration settings in the system that are not aligned with the requirements for using order BOMs.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check BOM Type:

  Verify that the superior BOM is indeed an Order BOM. You can check the BOM type in the BOM header data.

  If the superior BOM is not an Order BOM, you may need to create a new Order BOM or change the existing BOM type to an Order BOM.
  Use Transaction Code: CS01 to create a new BOM and ensure you select the correct BOM type.
  
  
  
  Review BOM Configuration:
  
  Check the configuration settings in the SAP system related to BOMs and production orders. Ensure that the settings allow for the use of Order BOMs.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to BOMs and production orders for additional guidance on the correct setup and usage.
