With enhanced grid capabilities with latest F&O version (10.0.38), any list page in F&O is almost behaving like an Excel. Currently, field can be made "Required" by simply personalizing the field. But if field is "Required" ONLY in certain scenarios then we cannot use this personalization feature, we need to end up with customization.

Instead of customization, this feature can be extended further to add conditional "field required" requirement.

For example: On project invoice proposals, Reason code and Comment fields are required for invoice reversals or credits only. In this case, if invoice amount < 0, Reason code and Comment fields are required.

I believe, this will help across all modules and is align with low code, no code policy.
