We try to understand the GP13 transactions that sometimes occur when we run the revenue recognition. In all our projects, we book the costs directly and calculate recognized revenue. From what I've read, GP13 is only used when calculating recognized costs (which we don't do).
It seems that these transactions occur when a project goes from positive to negative profit margin but I can't see any logic in the amount that the GP13 transaction gives us.
It happens that we run the revenue recognition several times after adjusting revenue/cost estimates.
Is this a bug or is there a good reason for these transactions?
