Explain Plan Issue

Hi,

I have built a calculation view based on combination of the other calculation views which have few calculated columns on the amounts and quantities.

Now I am trying to analyse the design performance by looking at the Explain Plan option.

Here having an issue that the explain plan is not showing till the lower level of plan.its getting restricted at the second level and not showing up all the dependent view/table information.When I remove the calculated columns its showing up till the lower level.

Please find attached.

Would you please recommend a solution for this or any setting do i have to maintain.

Thank you for understanding and support.

Best Regards

ERP
