• What is the cause and solution for SAP error message BOS01053 - Basic line missing for alternative line (data record &1) ?

  The SAP error message BOS01053, which states "Basic line missing for alternative line (data record &1)," typically occurs in the context of the Bill of Materials (BOM) or similar master data management scenarios. This error indicates that there is an alternative item or line in the BOM that does not have a corresponding basic line defined.
  Cause:
  
  Missing Basic Line: The primary cause of this error is that the alternative line in the BOM is defined without a corresponding basic line. In SAP, a basic line is the main item that serves as a reference for alternative items.
  Data Inconsistency: There may be inconsistencies in the BOM data, such as missing entries or incorrect configurations.
  Configuration Issues: The configuration settings for the BOM or the related master data may not be set up correctly.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (CS02 or CS03) and check the BOM for the material in question.
  Ensure that the alternative line has a corresponding basic line defined. If it does not, you may need to create or link the basic line.
  
  
  
  Create or Update Basic Line:
  
  If the basic line is missing, you can create it by adding the necessary data in the BOM.
  If the basic line exists but is not linked correctly, you may need to adjust the settings to ensure that the alternative line references the correct basic line.
  
  
  
  Data Consistency Check:
  
  Run a consistency check on the BOM data to identify any discrepancies or missing entries.
  Use transaction codes like CS15 (BOM Comparison) to compare BOMs and identify issues.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to BOM management to ensure that you are following the correct procedures for defining basic and alternative lines.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance, especially if this is a recurring issue or if it affects multiple records.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CS03 (Display BOM), and CS15 (BOM Comparison).
  BOM Types: Understand the different types of BOMs (e.g., single-level, multi-level, variant BOMs) and how they relate to basic and alternative lines.
  Master Data Management: Ensure that your master data management practices are robust to prevent similar issues in the future.
  
  By following these steps, you should be able to resolve the BOS01053 error and ensure that your BOM data is correctly configured.
