The Custom Fields and Logic app allows you to create custom fields for business contexts and enable them for UIs and reports that are relevant for the same business context1. You can also define logic for the custom fields, such as default values, validations, or derivations1.

If a customer needs detailed customization to the standard forms and email templates, you should propose to use the Output Management apps to customize a standard template. Output Management is a function that enables you to create, manage, and distribute output documents, such as forms, emails, or printouts, for various business processes in SAP S/4HANA Cloud. You can use the Output Management apps to select a standard template, modify its layout and content, assign it to a business object or output channel, and preview or test its output.
