0FC_RET Delta - ECC Side Scheduling

Hi-

I have been trying to run FS-CD Returns Delta from ECC to BW via DS 0FC_RET.  Unfortunately, I am not picking up the delta despite running the initialization.  RSA7 is not filling, RSA6 does show DS is Delta enabled.  That said, I realized it must just be a scheduling issue so I am trying to schedulee in FPOP/FPSCHDULER however, there is no guidance on what to chose in "Mass activity type" in FPSCHEDULER.

Any suggestions?

Thanks,

Mark
