Problem with Next Page(P+) button for VF02 during BDC(Call Trans)

Hi guys,

I have doing a BDC program that manipulates the pricind condition of a billing documents(VF02). Naturally we all know the process involves ticking the checkbox of the line item and press "Pricing" to enter the screen number 620(Pricing Condition page).

My problem is that if I try to call the BDC_OKCODE of 'P+' via call transaction in mode 'N', the process doenst run as planned. However, If I use mode 'A', and simulate the process, the BDC appears to work fine.

My superviosr claims the problem is due to related to the table control of the pricing page. My question is what can be done here?

Thanks guys and good day.
