Hi Reddy,
There are few dfferences between Accountng and Costing based COPA.
Some other points are below:
1. You Can't transfer variance to Accounting based COPA, where as it can be possible in Costing based COPA.
2. Costing based COPA is based on Char and Value fields. So, you can get a flexible reports. Whereas in Acc based COPA, you can't that flexibility in reporting because we use GL accounts for reporitng.
3. You can't get reports based on sales orders in Acc based COPA.
4. At the time of delivery of goods, revenue details will not update in Cost base COPA, but the same will update in Cost based COPA at the time of billing.
Hope you have a clarity with this.
