How to customize custom steps on SAS Viya SAS Studio

[ShenQicheng]

Hi,

I'm migrating Enterprise Guide custom task to SAS Studio and find that the best solutiong is to create a custom step with the same UI.

Using SAS Studio custom task is not an option because it can not be added to a SAS Studio flow.

Here are my challenges,

• when a column in a column selector control is selected, user can set some additional properties that is needed when generating sas code.
• the step has two input data and user can set the join conditions
• columns of the output data can be inherited from either of the input data or be calculated using input data

These functions are implemented on EG custom task by using c#.
On SAS Studio these can be done by combining some built-in steps with simple custom steps, but is it possible that I can create my own controls so I can implement all these functions in one step, so that user can do all these in a single custom step?

I am using Viya 2022.1.

Custom steps can be added to a flow:

From the documentation:

Note: The Custom Step functionality is available only if your site licenses SAS Studio Analyst or SAS Studio Engineer. Custom steps are not available in the Interactive perspective.

Thanks @DJongman .

I do know how to create custom steps and add them to flow.
I'm asking for solutions for the points that I listed in my first post that can not implement (or I don't know how) on the current version of SAS Studio
