can yo help me understand what does this preference do ? 
 Show Equivalent Consumption Status of All Objects in the Structure

When set to Yes what happens and when set to No what happens ?

Because if it is set to No then the error appears in the Bom Transformation. When set to Yes the error is disappearing . What is the meaning of this error ?

[Fadel · Accepted solution]

When set to 'Yes', the equivalent consumption status of all objects in the structure will be displayed in the 'Equivalent consumption status' columns. When set to 'No', only the equivalent consumption status of leaf objects and sub-assembly objects that are reused between the upstream and downstream structures will be displayed in the 'Equivalent consumption status'
