Hi,
I looked at APPS10 documentation but could find type Cust there as well, and I can’t remember I have ever seen it.
As explained in the documentation Trans type had a special handling in IFS Configuration Builder, but that tool is not used in IFS_Cloud. Also in the IFS Configuration Builder this information was shown in the tool, per component, but it was only informative.
So you can use Cust as before.
When running ifs_build with credentials given (if no credentials, creation of build home defaults to fresh install, creation of delivery defaults to VersionUpToDate), the logic is to connect to the database and check for the component and the version of the component. If the component doesn’t exist in the db, it will be a fresh install, calling cre scripts and the rest of the files.
If component exist, the version will be matched against the version in the [<component>Upgrade] section and defined upg file will be called.
Check the deploy.ini documentation about the [<component>Versions] and [<component>Upgrade] sections
