Extractors for accrual engines

Friends we are planning to implement accrual engine on the ECC. Wanted to get a few details-

What are the standard extractors in BW for accrual engine (found the following in some old forums not sure if these are still the ones to go for 0ACE_CALC_RESULT  and 0ACAC_CALC )

Is there any integration needed for this information with the GL or the area which is being accrued in our case POs?

Any detail or information in this area will be helpful. Thanks.

Thanks & Regards,
