• What is the cause and solution for SAP error message BOS03106 - Explosion not possible: selected item is not base object costing ?

  The SAP error message BOS03106 indicates that an explosion of a bill of materials (BOM) is not possible because the selected item is not a base object for costing. This typically occurs in the context of product costing and BOM management within SAP.
  Cause:
  
  Non-Base Object: The item you are trying to cost is not defined as a base object in the system. In SAP, a base object is usually a material or product that can be used as a reference for costing purposes.
  Incorrect BOM Configuration: The BOM may not be correctly configured, or the item may not be included in the BOM structure.
  Costing Variant Issues: The costing variant being used may not be set up to include the selected item.
  Material Master Data: The material master data for the selected item may be incomplete or incorrectly maintained.
  
  Solution:
  
  Check Material Master: Ensure that the material you are trying to cost is correctly defined in the material master. Verify that it has the necessary views activated (e.g., accounting, costing).
  Review BOM Configuration: Check the BOM to ensure that the item is included and that it is correctly structured. You can do this by navigating to the BOM transaction (CS03) and reviewing the details.
  Costing Variant: Verify the costing variant settings to ensure that they are configured to include the item in question. You can check this in the configuration settings for costing variants.
  Define Base Object: If the item is not defined as a base object, you may need to create or modify the material to ensure it is recognized as such.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on BOM and costing configurations.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CS03 (Display BOM), and CK11N (Create Cost Estimate with Quantity Structure).
