BW COPA without ECC COPA module

Hello,

What are the limitations if I implement a COPA modelisation in BW without COPA module in ECC. I have these modules implemented in ECC :

- FI-GL

- FI-AR

- FI-AP

- FI-AA

- CO-PCA

- CO-PC

Is it possible to make allocation cycles in BW in this case ?

Thanks for your help.
