setattribute using Remote Complex Object Instance Service in siebel not working

Hi,

We have a requirement to reset one of the attribute under child product to default value in Modify orders in case if it is set to value other than default value, we have created a workflow and used RCOIS service to achieve the requirement and attribute is being set but Action for related line item is not getting set and when open configurator it is showing Original value there in the Asset, not the value set in our Code, i'm attaching a workflow here, please check and let me know if im missing something.
