| # Printing EBOM and PBOM Consistency The differences can be the result of changes applied to either the EBOM or to the PBOM, after the EBOM has been copied to the PBOM. LN only checks differences between data that has been copied from an EBOM and the PBOM, not other changes to PBOM. LN checks four questions: Is there any difference between a line of the PBOM copied from the EBOM and the corresponding line of the EBOM (including deletion of the EBOM line)? Have any lines been added to the EBOM, but not to the PBOM? It is not possible to change the EBOM after the revision has been approved. Only exceptions can be modified. Have any PBOM lines been removed? Are there any differences between the line of the EBOM copy data and the line of the PBOM in the following fields?
