Message UCF6669 - First Consolidation data for Unit XXX in group XX error

Hi, we have been doing the consolidation process good until february, but in march with one unit occurs this error, and I dont understand why if the balance is in zero and the net movement for the same month is in zero too, the system is trying to run a first consolidation again.
