Does anyone know the difference between system-generated accounts which are CTA and CTA-Elimination? CTA-Elimination seems to be mainly due to consolidated exchange rates and are from the elimination JE. How about the CTA? There are no actual transactions related to it. Is this just for balancing the debits and credits?

you have different FX rates for asset and liabilities - and equity. For A and L it is usually current rate, for E - historical. CTA balances balance sheet between these two rates recording the difference (if any).

Thank you!
