How to update only one target field and ignore the other fields in Field maps (Transform Map)

[WA1]

Hello, 

I have created onBefore Transform Script to update target fields in certain conditions for example : 

// If type is "A" & discovery is "B" --> Update only the target field discovery
        if (source.u_type == "A" && target.discovery == "B") {
            target.discovery = "A";
        }

When I test, I find that in the target record, all fields are updated but I want only the "discovery" field to be updated.

So how can I ignore the update of the other fields in the Field Maps section and only update one field "discovery" ?

Thank you

Hello

you may plan to write two "On before" script with different order as shown below

1) First on-before script - Order as 100  

// If type is "A" & discovery is "B" --> Update only the target field discovery

if (source.u_type == "A" && target.discovery == "B") {

target.discovery = "A";

}

2) Second on-before script - Order as 200

if (target.discovery == "A") {

ignore=true;

}

Please Mark ✅ Correct/helpful, if applicable, Thanks!!

Hello, 

It didn't work, the update was ignored.

Hi, You can change your code as like below.

if (source.u_type == "A" && target.discovery == "B")

{ target.discovery = "A";

}else {

ignore = true;

}

Please mark as correct answer if it helped.

Hello, 

It's about the first condition if it's true I want to only update target.discovery and ignore the rest of fields.

I don't think the else is the solution, if I add it I won't be able to update fields if (source.u_type != "A" || target.discovery != "B" ) because I still have other conditions to manage.
