Currently in our SAP system I maintain rates in the TCURR table. I took it over. What I don't understand is why do I need to calculate all possible combinations and upload those rates as well. I would like just to upload all rates against EUR and let SAP calculate the amounts based on translation. For instance I upload 1 EUR=1.14 USD and 1 EUR=0.8 GBP, then why do I need to upload 1 GBP=1.425 USD ? The translation combination of GBP/USD is setup.
If the combination rate is not needed, then how does SAP react to this rate uploaded, it will use the rate or it uses the translation via the EUR rates ?
