I know that this can be done by looping over single items, yet this is not my intent.  Thu, 08 Mar 2018 15:22:00 GMT https://community.blueprism.com/t5/Product-Forum/Running-a-function-on-all-rows-in-a-collection/m-p/88704#M39209 OngunArisev 2018-03-08T15:22:00Z https://community.blueprism.com/t5/Product-Forum/Running-a-function-on-all-rows-in-a-collection/m-p/88705#M39210 Nope -  you have to loop your data to access and update individual rows.  Points to note: this will be far far quicker at runtime than when running in the process flow diagram - at full speed it will be as quick as .NET code looping a datatable.  Also, if you are a developer that knows .NET there is nothing stopping you from building something smart in a code stage (maybe use SQL against a datatable in some way to do what you ask).
