Thanks it is possible to explain me which transformer I have to use to trigger the next feature reader to perform snapping?
The output of the FeatureReader is what you need to snap.
In general terms this is what it would look like:
You can have a Where clause in the FeatureReader to select the workarea (assuming data for more than one workarea is stored in the same table).

Can you elaborate?
- What's the other process that's active on that workarea?
- How can you tell it's finished?

Hi,
I need to check whether particular workarea (municipality) data is QC activity is performed as we are maintaining one table in database to record this. If the QC completed then only this snapping functionality need to process by the user. Hope I clear your doubts.

Not really. How do you know the QC is completed? Is there some sort of record written to a table, or something like that?

Hi,
Yes I have another standalone table to check whether QC is done for that municipality

Okay, so check that first, with a regular PostGIS reader and then if it is done you can use that feature to trigger a FeatureReader to read the actual data, snap it and then a PostGIS writer to write it all back.
