I have a similar question like lot of you has asked above. I do have a custom table which contains couple of fields in an variable set.

It is basically a table inherited from CustomerService Table called "x_custserv_case". It has field called "cust_id".

We are able to use the Get Catalog variables to get the current value of that field. We want to update it once we get the value as we want to keep the field clean.

Does anyone have any suggestion on we can achieve that goal?  

Please note the record we are trying to update is not a request item or service catalog task. It is a table that belongs to the Customer Service Module inherited from the sn_customerservice table.
