COPA Assessment Cycles and FI Period closing.

Hi Gurus,

I have question related to the COPA Assessment cycles.

We have closed the FI Period 03 and running the COPA Assessment cycles. while running the same, for few of the assesment cycles are completed and for the rest of the few cycles it is error out stating the Period is closed.

Why it is running successfully for few cycles and why it is complaining for Period closing for the others. We are on ECC 6 Version of SAP.

Error out cycles contains Cost accounts and Asset Account GL Accoutns.
