I want to create BOM for my assembly, but item no's are different, how to create the item no. As per my BOM.
I assume what you mean is that the balloon annotations you attach to components in your drawing view don't correspond to their respective find numbers in the bill of materials.
this can happen if the drawing view is of a different configuration from the one assigned to the BOM table.
However, even if this is the case, if you right-click on the drawing view and select Properties from the context menu, then in the dialog that comes up, you check the checkbox that says "Link to bill of materials" and then pick the BOM table out of the list below the checkbox.
That should match everything up.
