Compound registration business rules

Batch fields allow for customization of compound registration business rules to suit each vault’s needs. 

In this article we go over batch field definition by the vault administrator. We cover adding new fields, editing and deletion of existing fields.

 

Formal chemical registration in CDD enforces batch (or lot) registration. Data associated with batches, such as unique identifiers, vendor information, date of synthesis, and chemists name, just to name a few, are stored in batch fields. CDD auto-generates several batch fields in any new vault, but these may be customized by the vault administrator to suit each vault's business rules and needs. Existing batch fields may be edited or deleted, and new fields may be added at any time. 

Moreover, batch fields apply to vaults with and without formal chemical registration, and are fully integrated with CDD’s data import and validation, allowing each group to ensure that pertinent batch-level data is captured correctly for any newly registered batches. As a best practice, we recommend that you consider your molecule and lot registration process and requirements as soon as you subscribe to CDD, and define your custom list of batch fields before importing compound libraries.

 

Batch Field Definition

Here's an example of one vault's batch fields, utilizing all of the available settings. We will refer to this screen-shot in the table below, describing the options.

Setting	Description	Editing
Name	Pick a unique name for the field. This name will appear throughout the application. Include units of measurement for numeric data: see "amount" example in the screen-shot above.	Changes apply to existing and new batches throughout the application.
Data Type	Set the kinds of values that are permitted for a given field. Date: fields of this type accept values of acceptable date formats, which include MM/DD/YY; Month DD, YYYY; YYYY/MM/DD; MM-DD-YY. Number: fields of this type accept only real numbers, excluding numeric modifiers such as >,<=, etc. If you plan to store numbers such as >95, consider using the text data type. Text: fields of this type will accept any alpha-numeric values. File: fields of this type will accept file attachments of any format and size. Image and PDF files will be rendered with previews, all others will appear as downloadable hyperlinks.	Not editable if there are values in the database.
Must be Unique	Check this flag to ensure that values in the field are unique across the vault (batches/molecules/projects). This is a good way to designate additional batch identifiers, such as lab notebook number or vendor lot number: see "external identifier" example in the screen-shot above. For multiple unique fields, values are validated within the scope of each field, but will not be checked across fields.	Changes are prospective: applicable to new batch registration, and upon manual editing of existing batches.
This field is	This setting determines how this field is to be populated during new batch registration. Autogenerated: you may not edit or delete such fields. See "Batch name", and "Formula Weight" examples in the screen-shot above. Both legacy and new batches will be populated. Required: ensures that a value must be supplied on new batch registration. Optional: ensures that it is available throughout the application, but the value may be left blank on new batch registration. Conditionally Required (or <another field> is required): ensures that one of several fields is required, while others in the group are optional. In other words, a value must be supplied for one of the grouped fields, but all of them may contain values as well.         To set two or more fields as conditionally required, choose "or <field name> is required" from the drop-down: you will notice that all affected fields are updated when you do so.	Changes are prospective: applicable to new batch registration, and upon manual editing of existing batches.

 

Add a New Field

Batch Fields are defined only by the vault administrator, and apply to all molecules and batches across all projects in the vault. 

Click on “Add/Edit Batch Fields” on the Registration Rules sub-tab of the Vault Settings page.

At the bottom of the current list of fields, click on the “Add a batch field”, enter a unique name for the field, and set the available settings: data type, uniqueness flag, and required/optional status. Do not forget to save your work by clicking "Update batch fields" button.

A newly defined field will appear throughout the application, even if there is no value for this field on existing batches: in the import interface, on the search page keywords drop-down and results table, as well as in batch details view, and new batch registration form.

 

Edit an Existing Field 

The steps to edit an existing field are similar to adding a new one. Once in edit mode, change the settings that are available to you. Note that if any data is stored within the field you are editing, you will not be able to change it's data type. Field name change is applied to all batches, but if you are changing field requirement or uniqueness, the new business rule is prospective, meaning it will not apply to previously registered batches. Manual editing existing batches will enforce new rules. Batches may be updated to compliance either manually, or via file import.

Remove an Existing Field

In edit mode, click “Remove” next to any batch field. Caution: when you remove an existing field, you are permanently deleting all the values stored in that field across the vault. You may want to do a back-up of your data before deleting a field.

 

Order Fields

In edit mode, rearrange fields by clicking the “drag” icon. The order defined on the Registration Rules tab will determine the order of fields in the rest of the application, including the batch creation form, and the search page.
