Hello,

I'm passing a load of lines through an FME workbench and eachline has a project name as an an attribute. I want to add an attribute that counts how many lines are in the project (share the project name). Does anyone know how to do this?

I've tried playing around with the counter but have had no luck. what I need is it to separate out into all the different projects, use the counter, then chuck everything back together. I would use a filter but there are hundreds of projects.

Any ideas?

Thanks

Hi,

I think the StatisticsCalculator can be used (Group By: project name).

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Hi,

you can set the "Counter name" to the name of your attribute. It will behave like a Group By and keep track of one sequence per unique attribute value..
