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 there are no matches to the modified structure an empty Suggestion list will appear where the new structure is displayed as a "New compound" (similarly as it is in the case of Parent level amendment). By clicking the [Register as selected] button, the structural change will be saved and all the lots that belong to the modified version will be moved under a new parent tree receiving new Ids.

Stereoisomer, tautomer and stereoisomer & tautomer match

Stereoisomer, tautomer or tautomer&stereoisomer matches, if available, are displayed on the right side of the Suggestion list. All the lots that belong to the modified version will be moved under a new parent tree receiving new Ids.

New Ids will be received, if "New compound" is chosen before clicking the [Register as selected] button. If a suggested structure is chosen, all the lots that belong to the modified version structure will be moved under the chosen version structure and will receive new Ids.

Amendment of single compounds used in multi-component compounds

Currently, editing compounds on version level that are part as components of multi-component compounds is not allowed.

Amendment of multi-component compounds

The amendment of multi-component compounds is allowed. The lots that belong to the modified version will be moved under a new parent tree receiving new Ids.
