To pass SYSDATE when you upload a DFF using FNDLOAD

The dates or rather the entire RowWho information will be passed in from Source System, i.e. whatever is in the ldt file.
Open the lct file by doing
vi $FND_TOP/patch/115/import/afffload.lct
search for string fnd_flex_loader_apis.up_desc_flex
In the parameter last_update_date you can pass sysdate, replacing the value read from ldt file
