Hello, I wrote a little how-to on adding a new parameter to any dataset, this one is for a report, but it should be helpful to guide you: SSRS - Feeding report style number/description into RDL - #8 by GabeFranco
My example is using the Job Traveler report, Erp.Rpt.JobTravSvc/SubmitToAgent, but the logic is generic and applies to any report.
Here, I am pulling an existing variable “ReportStyleNum” and using it in my Pre BPM.
You will need to customize the Kinetic UI form to add a textbox to send an extra field into the pre - Maybe you can bind the textbox directly to callContextBpmData.Character01 - or you might have to pass it in another way and then in the pre, set it into Character01.
Either way, once you get the value into callContextBpmData, you can then use it.
I’m not sure how you would want to use this new variable in the process.
