Why don't you ask your training department?
JHR,
Excellent question! And, 'back at you'...why don't you ask two questions of your training department:
1. Do you perform ECAM first, then OEB, etc., etc? (Your original question)
2. Will you please reference your answer to an authoritative document?
Now, to answer your question. (Disclaimer....I am retired and do not have access to the 'new format' FCOM. So, my page numbers will be different.)
Please refer to FCTM OP-040 P6/10.
Please refer to FCOM 3.07.10 P1/2.
In summary, you apply the OEB, NOT the ECAM. "The flight crew must disregard the ECAM procedure and/or STATUS of the ECAM alerts listed in the "AFFECTED ECAMs" flield and must apply the QRH's OEB procedure instead. If the operator uses the OEB REMINDER function and has activated the OEB REMINDER function onboard for the affected ECAM alerts, the ECAM informs the flight crew to refer to the OEB procedure in the QRH by displaying "REFER TO QRH PROC" and/or "FOR STS REFER TO QRH" line (Refer to the OEB reminder section for more information).
Actually, on the subsequent page of the FCOM, we are warned to cross check the OEB to any TRs that may exist in the Airplane Flight Manual, as the AFM and related TRs take priority over any other publication. (As is normal.)
So, your primary instruction was incorrect....Again, I strongly suggest you address your questions to your training department, as responses you received here in PPRune may my be incorrect, or may be correct for some operators....but, not yours....so, get the correct information vis-a-vis your company's SOP.
Then, when getting an answer, ask to see an authoritative document to support that answer.
Fly safe,
