Now my requirement is based ona status i want to remove a value A from the field by keeping the values B and c.

But i am already using BR to add the vlaues to the field, as i am doing a integration and 3rd party gys will be sending me those field values to a table and based on that tbale record i am populating them in the RITM.

code will look like this provided you are trying to nullify or set the values.

if(ga=='Retired') {

current.host_name = ''; // whatever value you need to set here. example host_name = 'A';

current.ip_address= '';// whatever value you need to set

current.update();

}

I dont want to Nullify the value just want to wipe out one value which is in the value,

Ex: Value =   asdfghjkm,bfgbjhnkm,mvgghjfgf.

Out of those three coma seperated values i want to remove just the First value before Coma.

Thanks

Please check if something like this helps. sample script.

var final_value = [];

var value=   ['asdfghjkm', 'bfgbjhnkm', 'mvgghjfgf']; // replace line of script with var value = current.field_name

var valsplit = value.split(',');

for(var i = 1; i < valsplit.length; i++){

final_value.push(valsplit[i]);

}

Inspired from Shishir's code, which contains an error : Shishir assumes the current field value is an array, where I assume it is a list :

//initialising an array for your data manipulations

var finalValue = [];

//given field value = 'asdfghjkm', 'bfgbjhnkm', 'mvgghjfgf' : assuming it is not an array, but a list

var myValue = current.<fieldname>;

var valSplit = myValue.split(',');

for (var i = 0; i < valSplit.length; i++){

        if (<you want to run a test to know which value you want to keep or discard, then test selects values to keep, for using push method>){

                  finalValue.push(valSplit[i]);

        }

}

//then you want to join to have again a list from your array

current.fieldname = finalValue.join();

current.update(); // you can omit this in a before business rule

This is if you want to remove A, B or C, based on a test.

If you just want to remove A, ie the first element of the array, use the shift() method instead of a loop :

//initialising an array for your data manipulations

var finalValue = [];

//given field value = 'asdfghjkm', 'bfgbjhnkm', 'mvgghjfgf' : assuming it is not an array, but a list

var myValue = current.<fieldname>;

var valSplit = myValue.split(',');

valSplit.shift();

//then you want to join to have again a list from your array

current.fieldname = finalValue.join();

current.update(); // you can omit this in a before business rule
