PO item interval issue

Hi, expert

Do you know how to make the PO item interval the same between SRM 7.02 and ECC 606?

My scenario is classic and the PO will be create in backend system.

I created PO based on RFx response and the PO in ECC has the item interval as 1,2,3...

While normally in ecc, my item interval is 10,20,30.

How to change that. I searched in system , somebody said the badi: BBP_CREATE_E_PO_NEW can realized that, is that true.

Thanks in advance.

Regards,

WuLin
