I'm currently building a stock & POS application using APEX 18.2. One of my pages (as shown below) contains an Interactive Grid. It has a validation named 'Goods In-Flow Unique Key Validation' having Execution Scope 'All Submitted Rows'.


But when trace using Debug Mode, it shows that the validation was only executed once, which I assume because I only modified 1 out of 4 rows.
Is this how 'All Submitted Rows' is supposed to work, or am I missing some other settings/configurations?


Thank you in advance for any attentions & helps.
