Found the answer thanks to Google.
Pasting it below for ready reference in case someone is not aware of Sed Branching like me
Code:
$ sed ':label command(s) t label'

:label - specification of label.
commands - Any sed command(s)
label - Any Name for the label
t label - jumps to the label only if the last substitute command modified the pattern space. If label is not specified, then jumps to the end of the script. 
b label - jumps to the label with out checking any conditions. If label is not specified, then jumps to the end of the script.

---------- Post updated at 10:19 PM ---------- Previous update was at 01:11 PM ----------

The code using sed :up
s/\("[^,]*\),\(.*"\)/\1!@%\2/
t upwill not work properly in case the input record is of this type
Jacuzzi,"Jet Rings!@% Pillows",Accessory,"abc,def",Optional,,9230917,69094,,P556805,69094,FALSE,1,0,,
i.e if there are multiple columns with double quotes the sed command will fail.
any ideas how to over come this limitation.

Thanks for your help in advance.
