Convert BR script into Custom Flow Action

[Anderson_R]

I'm trying to convert the following BR into a custom flow action with a script step. However, I'm having difficulty putting it together. Any help with the input variables, script, and output variables would be greatly appreciated. 

The business rule I'm trying to convert: 

(function executeRule(current, previous /*null when async*/) {
	// Call the script include
	new global.u_AttachmentUtils().copyAllAttachmentsToMe(current.parent.sys_class_name.toString(), current.getValue('parent'), current);
})(current, previous);

What I currently have in my flow action, but isn't working: 

Any help is greatly appreciated!

Hi @Anderson_R ,

When looking at the business rule, you have 3 parameters.

the 3 parameters are derived from current object. When the input is given to the action step, you need to make sure that it is the same object.

For more details about how to populate the input and generate output, please refer this link.

and this link as well 

And let me know, if you need more assistance.

Thank you.

Karunakaran.

Hi Karunakaran, 
Thanks for the reply. Yes, the parameters are derived from the current object. So with one of them being current.parent, is this how the input would be configured for it?

Considering:

yes, here you can define the type of inputs as per the parameters in the method you have.

In the previous step for the action, you need to make sure the inputs are given correctly from the data panel.

Please let me know, if this is confusing.

I currently have the parent field defined as a reference name. Does this look correct? I don't see a way to ensure it's retrieving the parent from the current record. 

Then for the second parameter, it's not found directly on the current record. I would have to dot walk to it from the current record. As the BR uses current.parent.sys_class_name. How do I create an input for a field that you need to dot walk to?
