Currency conversion via routine in transformation BI 7.0
for an international data model we want to translate currencies via data load using a routine in the transformations. We are thinking about creating 2 key figures for local currency and group currency. Group currency is always EUR. We found to function modules but we are not sure about the differences and if we can us them at all: CONVERT_TO_LOCAL_CURRENCY and RSW_CURRENCY_TRANSLATION
Does anyone of you implemented currency conversion in a transformation before using a routine. And does anyone have experience with those function modules and can explain the differences? Thanks a lot in advance! Any help is appreciated!
