Adding custom fields in ESS Infotype 23

Hi all gurus,

I have followed the steps from the below document :

Adding any Info Type IN ESS in EHP5/6 through WebDynpro Configuration

All the fields from IT0023 are showing in ESS. Now the problem is in the R/3 , there are some custom fields which is not showing in the ESS.

Please guide on how to bring those custom fields into ESS.

I have 1 more doubt. Here there are some custom infotypes like 9001, 9002 etc.. Is it possible to bring those infotypes into ESS.? How..??

Thanks ,
Namsheed.
