Customize ESS..NWDI info reqd.

Hello All,

I am using EP 7.0 with ECC 6.0 and ESS 1.0.

The applications are working fine. now i want to customize some of the applications say..Bank Info.

I searched the forum and found it can be done using NWDI. I am aware of NWDS but not NWDI.

will request someone to update me on this.

If this required some seperate installation, what all files need to be downloaded and from where?

And how to open the package ESS 1.0 in it to customize it.

regards

Justin
