Make requested date and promise date editable after quote creation

[carbon-agent]

Problem

Currently, the requested date and promise date fields on quotes appear to be set at creation time but may not be editable afterward. Users need the flexibility to update these dates as customer requirements change throughout the quote lifecycle.

Proposed Solution

Make the requested date and promise date fields editable on existing quotes:

• Allow editing via the quote details/properties UI
• Preserve existing validation (e.g., requested date should not be in the past)
• Update any dependent logic that assumes these dates are immutable

Context

• Screenshot shows quote interface with Order Date, Requested Date, and Promised Date
• Requested Date: Sep 14, 2026
• Promised Date: Sep 14, 2026
• Both fields have calendar picker icons, suggesting they should be editable

User Story

As a sales rep, I want to update requested/promised dates on existing quotes so that I can adjust commitments as customer needs evolve.

Priority

Medium — affects quote management workflow flexibility

Can I work on this enhancement?

Just saw the UI and understood the problem with the Requested Date and Promised Date.

Just wanted to confirm can I take up this Issue??
