How to Add Date Information After Activating a Migrated Lease Contract

Content (please ensure you mask any confidential information):

After registering the Migrated lease as active in FBDI, we received a request to add the following date information:
・Document Start Date
・Document End Date
・Signature Date

These three items were initially registered as blank fields during system deployment, but we received a request to add them after deployment.

We attempted to use the “Lease Modification (Non-Financial Data)” function, but only the “Document End Date” field was editable; the other two fields could not be modified.

How should we resolve this issue?
