can you specify in which D365 CE application you work and in which table the field is locked for this users? Can you moreover clarify, if configurations/extensions are used? Basically, the following behaviors can have impact on a fields "Write" status, if an user is not able to edit/overwrite it, even when it is a commonly used field:
1) Field-Level Security
- Go to Settings > Security > Field Security Profiles
- Check if "ManualDiscountAmount" is enabled for field-level security
- If yes, ensure the user’s security profile has read/write access to that field
2) Form Customization
- Navigate to Quote Details form in Power Apps or classic customization
- Open the form and check if the field is set to read-only
- Also check if any business rules or JavaScript are disabling the field
4) Business Rules or Workflows
- Check for any business rules that lock the field based on conditions (e.g., quote status, discount type).
- Also review Power Automate flows or classic workflows that might be affecting field behavior.
5) Form Behavior Based on Status
- Some fields are locked when the quote is in a certain status (e.g., Approved, Submitted).
- Try editing a quote in Draft status to see if the field becomes editable.
6) Custom Plugins or Scripts
- If your environment uses custom plugins or JavaScript, inspect them for logic that disables the field.
- Use the Form Editor > Events tab to check for scripts on load or change.
To get a more fitting answer, provide full screenshots with the (whole) URL/URI visible and/or more detailed information.
