Hi Shweta,
you have not mentioned that you have added this custom tab in header lecel or
at item level, if it is in header level, it will be in GOHEADER structure, if it is in item level
then you can find it in GOITEM structure.
Please use transaction OMJX, and choose the structure you have added for your custom field.
Please check the Display, button for the added custom field, you might able to see your custom added
field there.
