#Record Identifer , identifiers for Process Backed Records
Reading this link forum.appian.com/.../Records_Tutorial
shows how to create identifiers with Source Type Rule and use identifiers.
How can we use Source Type Process Model and use Tags and keep identifiers , any detailed explanation of this.
1. Have a process model based record
2. In the news i currently post the link to record which is a big url.
3. I want to use record tags instead of that big link in the news.
4. to use a!toRecordIdentifier , the 2nd argument seems identifiers which are specified in the Record Type.
Thanks...
