Document ID field in ServiceNow

Hey There!

Today we'll discuss an interesting thing provided by ServiceNow. At times we need to specify a reference column without knowing what will the table be. It might be an Incident to refer, or a change, or some other user defined table. But our very own reference field doesn't let us do that.

For that, ServiceNow has provided as the Document ID field. A Document ID field is of two types -

1. In which we can let the user specify the table name in another column created by us - known as Dependent column.

2. A field in which we have a table and a field drop-downs to choose from.

I'll show you how.

USING DEPENDENT COLUMN

First, we will go to the table where we want the Document ID field. Create a column of type Table Name with your choice of name. This will be used as the dependent column where the user will specify the table name to reference.

Next, create a column of type Document ID. Save it. Under the column Dependent Field, check the box Use Dependent Field. Under the drop down Dependent on Field, choose the field you created for table name to reference.

And...its done :) ...when you'll go ahead and add a new record to the table you'll be required to add the table name and then you can go ahead and choose the record from that particular table to refer to.

Without using the Dependent Column

Just don't check the column Use Dependent Column and add the values by selecting the table and record.
