  The SAP error message IB_DECO127 indicates that a specific material (denoted as &1) is not assigned to the installed base (denoted as &2). This error typically occurs in the context of Installed Base Management (IBM) within SAP, where materials are linked to installed bases for tracking and management purposes.
  Cause:
  
  Missing Assignment: The material you are trying to associate with the installed base has not been assigned to it in the system.
  Incorrect Configuration: The installed base may not be configured correctly to accept the material.
  Data Entry Error: There may be a typographical error in the material number or installed base number.
  Material Status: The material may be in a status that does not allow it to be assigned to an installed base (e.g., inactive or blocked).
  
  Solution:
  
  
  Check Material Assignment:
  
  Go to the Installed Base Management transaction (e.g., IB01, IB02) and check if the material is correctly assigned to the installed base.

  Review Configuration:

  Ensure that the material type is compatible with the installed base.
  
  
  
  Check Material Status:
