Often customer recieve data from their clients to produce the parts. These data have a lifecyle history in the sending environment, i.e. "C.7". To keep this history in the collecting system, here 3DX, is important to 

a) avoid any mismatch in the BOM, i.e. to source the right parts

b) to ensure the history, if some modifiations are needed for production, to reflect to the right basis

c) in the case of migrating from older systems or foreign systems to 3DX.

Unfortunately we don´t have any mechanism at import to start the revision history by the sending revision histore. Do you have any idea to cover this case? Many thanks in advance.
