ME22 BDC Recording

Hi,

I want to use a BDC recording of ME22 to do the steps below. The problem im having is that I can do these steps in ME22 but when I try to create the recording using SHDB different windows come up, its taking me to the account assignment of service

when I click back its asking for an account assignment and I dont know how to proceed. Any ideas on how to do the steps below with SHDB?

Steps:

ME22> Enter the PO > click overview icon > select item > click edit > Reset deletion ind > select item > click on services icon > change gross price > click back > select row > click on delete icon > Click Yes on the caution popup(Caution! the selected items will be deleted) > Click Save.

Thanks
