It has to be part of the data dictionary that the BOI uses. Get with whoever created the module and find out if they undated the data dictionary and system files also so that it can be used with BOI.  (What enhancement is it and from whom)

Thanks for the reply BigLouie I will check.

Hi BigLouie, I found the _bus file in the source folder and I used the same object in the code, Still it's giving an error "Exception has been thrown by the target of an invocation"  Do you have any idea about this?

Some business objects are not intended to open directly (eg. SO_InvoiceDetail_Bus, which you have to access as oLines through SO_Invoice_Bus).

Consulting with the Master Developer who created the module is the best way to get answers (as BigLouie indicated).

Thanks for the reply Kevin M That's better Idea to talk with Master Developer.
