Version level amendment
In a version level amendment (VLA) all type of changes, involving isotopes, charges or salts/solvates, converting structures to multi-component compounds, adding CSTs or additional data are allowed.
When amending a version, the structure and all lots that belong to it will be always moved to another (new or matched) tree and new version and lot level Ids (CN, LN) will be received.
Amendment of single compounds
No match
In the case when the amendment was initiated from a version structure, and the version is the only version of the parent, and there are no parent matches to the modified structure, the PCN will be kept for the modified structure.
Exact match
Independently from which level of the tree was the amendment initiated (parent, version or lot level), if there is an exact parent match, a the match list with the match(es) will appear. Even though it is possible to have a match list with several matches, the exact match will be the very first in the list. In this case only the Accept option (no other options at the rest of the matches) will be available at the exact match, or the amendment process can be cancelled by closing the match list.
If the exact match is accepted, a Summary window appears reporting the eventual creation of a new version and the movement of all the lots from the original tree to the accepted tree. If the accepted PCN doesn't contain the version from the original tree, a new version will be created and all the lots from the original tree will be moved under it. The original tree will be kept the empty version (containing no lots).
2D, tautomer and 2D&tautomer match
In case of 2D, tautomer or tautomer&2D matches (if exact match is not available), two options will be available: unique and accept
Amendment of single compounds used in multi-component compounds
Editing single compounds used in multi-component compounds on version level is not allowed.
