ChemReg customer might be interested in mapping Corporate ID and Lot ID for file registrations by including values for these attributes in the SDFile, but they will find that only those attributes that are available on the registration entry form are available for mapping for file registrations.

However, for enabling Corporate ID mapping, they can modify the Bulk Registration Attributes. This extension controls which attributes are available for mapping on the Attributes page of the File Registration tab in the Chemical Registration web client. The following example is shown under Common Customization in ChemReg Developer Guide:

"Allowing Mapping of the Corporate ID Attribute

1. Edit the Bulk Registration Attributes custom component.
2. Edit the Expression parameter of the File unwanted properties component in the subprotocol to remove the filtering out of the Corporate ID-named attribute at line 6:

    5 if #ok then
    6 #ok := Name ne 'MolecularWeight' and
                  Name ne 'CorporateID' and
                  Name ne 'PreviousIds';
    7 end if;

3. Complete the steps for Customizing Extension Components.

Tip: Filtering of attributes uses the Name of the attribute, not its Display Label."

Please note that there is no provision for Lot ID mapping in ChemReg because values for this attribute are auto- generated.
