How to bill/invoice in RTP billing scenario

Hi guys,

I'm new to RTP billing and need your help. I have already setup everything for RTP billing:

1. created EDM profile header

2. allocated the profile header to a device

3. uploaded values into profile

4. created RTP component

5. created RTP interface

6. created RTP operands, rate, schema, rate category, rate type, rate determination

7. created IS-U master data and move-in

8. checked the installation for billability via easich

My question is: how can I bill and invoice this installation? I cannot do it with EASIBI, because

a.) if I tick the "Enter billing order/ME results" checkbox, I get the "entry of meter readings not possible" message.

b.) if I don't tick the "Enter billing order/ME results" checkbox, I get the "No billing order exists for contract ..." message.

Of course meter reading entry is not necessary, but then how do I do it?

Thank you,

Regards,
