Hi Sanjay,
Try replacing the 4 backslashes with just 2. Usually works with 2
backslashes.
Replace this *split(reverse(split(reverse(**floc**),'/')[0]),'\\\\.')[0]*
as resid
with *split(reverse(split(reverse(floc**),'/')[0]),'\\.')[0]* as
resid
Please have a look and let us know if that helps.
Best ,
Vivek Veeramani
