  • Hi guymalka,

    when you set the field value to null than this means that you don't want to update this field.

    To bin in Adis posting in your code you have to write this code:

    <instance.customized field name> = new Picklist();
    <instance.customized field name>.IsNull = true;
    <instance.customized field name>.IsNullSpecified = true;

    crmservice.update(instance)
