Generation Error while Building DC

[Former Member]

HI All,

When we try to build a DC from NWDS we are getting Generation Error. We have build all the Used DC's and all are build successfully.

Before this issue we have created new view and done few mappings. Becuase of some other problem we we have deleted view but mappings are not deleted. While building as the mappings are available & view is not exist then it's it's throwing build error.

Fix:

We have removed all the mappings related to that view and build again then it's working fine.
