Hope I'm not butting in but I've been practicing this lately. Is your question that you want to send money from your external current account into your Rabo Saving A/c? If it is then to the best of my knowledge you need to go to Rabo, then Money In and then Money Mover and Create.
You then select your Rabo Savings Account** to credit and click on Next. At that point you enter the sort code of your external account and your account No. The next page tells you to enter the external account name (your own presumably) and that's is. On that page you can recheck the sort code and acc. no. The final page asks you to state the amount you want transferred, the date of the transfer you are setting up and you enter whether it's single payment or a regular amount to be sent to Rabo. I imagine if you don't enter a date for the transfer it's sent in 2-3 days. (Basically Rabo debit your external account for the amount to be transferred.)
Apologies if I've got the wrong end of the stick!
**As everyone knows by now, when taking money out of Rabo you have to first transfer it to the Rabo current account and then on to the external bank
