Sub Forms within a Sub Form

Sub Forms within a Sub Form

Hello,

I need to store two levels of master details in my form. For example I need to store with a Purchase Order, PO Header and PO Details such as item wise quantity ordered.  However I need a further sub-form to capture the break-up of quantity ordered into customer wise requirements.

Is it possible to store sub-forms within a sub-form.  Is this functionality supported in C5 version.

Another issue is to add the required number of rows in sub-form at the time of data entry based on the requirement. I do not know in advance how many rows would be there in my sub-form. Is it possible to do the same. What is the script for that.

Thanks for your help in advance.
