Hi Gurus, There is a scenario to load hierarchy thru flatfile. How can I load hierarchy to 0DATE from flat file?

I can create a datasource & when i try to create a transformation to it says, 0DATE is not switched infoprovider property. but in the 0DATE infoobject how can I switch it as infoprovider? it doesnt have master data tab?
