How Extend and keep the validation the standard fiori Manage purchase Orders app in SAP BAS?

[Anjan_3331]

My requirement is to add company code and material as mandatory fields in the Manage purchase order standard fiori app in SAP BAS. If user clicks on "GO" button without any input needs to validate.

I have created adaptation project from BAS and imported the standard app from ABAP repository and opened in Adaptation view.

May i know which option i need to use to keep the validation ?

Please find the attached screenshot and help me.

Thanks

One possible solution is to create a Metadata Extension for the consumption view and add @Consumption.filter.mandatory annotation to the fields that are mandatory.

Most apps don't support metadata extensions. However, this can be achieved through local annotations, as they are already using an adaptation project.
