I urgently need to know why status is not getting importing when I'm tryiing to import ticket's into the sdplus tool.

all other details is imported correctly apart from the status.I've tried many time to copy and paste, even manually typing it more than 10 times. But it doesn't get updated correctly for 80% of tickets.

I need to know this urgently as we are going live tomorrow and need this resolved by today. 

Thank you.
