is there an expression to differentiate SELECT vs ADD in arcade expression?

[WilsonLee]

in Field Maps Arcade Expression, how can I differentiate between "selecting an existing point" and "adding a new point" within an Arcade expression.

I'm trying to apply a  different code based on the action selected by a user (SELECT vs ADD) from a same layer.

currently, i have setup 2 layers in field maps for "Updating" and "adding a new point", but would like to combine them and make it more convenient for user. 

thanks,

Wilson

Hello,

I believe what you are looking for is the edit context/edit type.  It is a profile variable found in the Form Calculation and Form Constraint Arcade Profiles

https://developers.arcgis.com/arcade/profiles/form-calculation/

https://developers.arcgis.com/arcade/profiles/form-constraint/

Your Add is INSERT and your select is UPDATE.

// Example usage of $editcontext.editType

if ($editcontext.editType == 'UPDATE') {        
    if (!IsEmpty($originalFeature)) {
        var oSelf = $originalFeature.rsrc_previous_feature_info;
        var oServiceNumber = $originalFeature.service_number;
        if (oServiceNumber == serviceNumber) {return oSelf};
    };
};
