Mapping Issue

Hi Experts,

we are working on ECC-PI-DATABASE

your requirement is we have one field in sender side (Deletion indicator) in ECC some times in this field have the value and some time doesn't have the values.

If the field have the value we process otherwise we will process  null value to target stretcher

I tried using EXISTS node function and equals function and ifwithelse function but i didn't get

Please let me know how we configure in mapping level

Thanks,

Raju
