I need to create unique Ids for a point feature class. Also, when a new point is added to the class I need to the unique Id created automatically when the workspace is run. 

I have created a workspace that includes the File Geodatabase Point Feature Class Reader then the Counter Transformer to create a new field named _count and a new field in AttributeManager named Facility_ID. 

 

All the unique Ids will be formatted as follows: BLDG-000000001, BLDG-000000002, etc…

When a new Building Point is added to the Feature Class, the Facility_ID field will automatically be populated with a unique ID in sequence increments of 1; example if the highest unique id in the feature class is BLDG-000000109, then when a new building is added it’s unique id will be BLDG-000000110.

 

What else do I need to do? any assistance is much appreciated.

I figured it out. 

I used the Counter to generate the unique numeric ids; 

I then used the StringPadder to add 9 zeros to the left;

In Attribute Manager I added the Facility_ID field calculated with “BLDG@value(_count) the result is the following values: BLDG-000000001, BLDG-000000002, … , BLDG-000000010, …, BLDG-000193426

 

When a new point is added in ArcMap, this workspace is run and the output has a new unique ID for each newly added point. 

 

Note in my screenshots I did not include the writer, since I am in the dev phase of this workspace. 

 

If anyone has another way to do this, please share.
