Showing multiple error message at one time on CRM Web UI

Hi experts,

I have created 3 new fields on the CRM web UI using AET tool, we want to give error message depending upon the value filled on the fields.

I am using ORDER_SAVE BADI to give my own error message.

I am passing CV_OWN_MESSAGE as X and giving my error message but it takes only one message how can I collect more than one message and show it on the UI.

Like

Fields one is not correct

please select a value for field two

Field three should be sum of field one and two.

Any help would be highly appreciated.
