Mapping Issue

Hi Experts ,

Am facing with an issue

for an logic

if RED_CIR_CAR_ENDAT  (RED_CIR_CAR_ENDAT ) = DECODE(TRUE, NOT ISNULL(v_RED_CIR_CAR_ENDAT) AND SUBSTR(v_RED_CIR_CAR_ENDAT,1,5) != '00000' AND SUBSTR(v_RED_CIR_CAR_ENDAT,1,4) != '9999',

Then it should pass or else it should be empty ..

SUBSTR(v_RED_CIR_CAR_ENDAT,1,4) || '-' || SUBSTR(v_RED_CIR_CAR_ENDAT,5,2) || '-' || SUBSTR(v_RED_CIR_CAR_ENDAT,7,2))

For this i have created like this
