Hi Tanweer
you get this error under two circumstances
1. The key figures showing ERROR are not filled with any currency . If this is the case make sure you have valid currency populating at transformation level. If you dont have this luxury then you can mark the key figures NODIM in BeX to avoid this error
2. There are records in multiple currencies. Therefore they are not getting aggregated at BeX level. You cant add 1 euro and 1 dollar. Use NODIM in this case also.
Thanks
