SAP S/4 HANA Cloud - GL account creation in copy in quality system

Hi,

I'm trying to create a GL account in copy of other one in "Manage G/L account master data" app in quality system (SAP S/4 Hana Cloud) but "Changes not possible. The configuration is locked" error appears.

Can I create GL accounts only in development system and transport these changes in quality system as a configuration task? or is there another way to create the accounts directly in the quality system?

Thank you in advance.
