This can occur when two currency values of transactions match but the sterling values have not been entered the same, so when you allocate them together in currency, the system allows them to allocate (as the currency values match) but as the sterling doesn't, the difference is then created into the Rounding Difference account.
Normally, this would be a few pence, but if the sterling values are very different, then that difference will be used for this rounded value.
If you have checked the sterling and currency values are correct, but you still get this rounding error, we may need to look at the data in the back ground to correct incorrect allocations, which may occur when transactions are allocated, unallocated, then reallocated again elsewhere.
To resolve this - our support team will need to investigate, run scripts or liaise with the hosting or development teams. Any Issues with contacting us, please see the following Get support in Dimensions.
