Yes Shivani.

I want to automate loading and tranformin on  form button(UI Action)

How data is fetching into system and what type of file will it be? ..CSV

It can be done through data source and schedule this data source on demand basis.

In UI Action, you can call the script to run this scheduled data source basically you can call "Execute Now" ui action script for this data source.

Mark helpful if it resolves the purpose.

Thanks its helpful.

But in my case , its custom table form -- I am adding attachment on it.

How do I attach the workflow - on which condition ??

Hi,

Since that is your custom table and attachment you can use that same script in the UI action itself

your UI action code would look something like this

GlideSysAttachment.copy(current.getTableName(), current.sys_id, 'sys_data_source', '<dataSourceSysId>');

var exportGr = new GlideRecord("scheduled_import_set");
exportGr.addQuery("sys_id", "<RecordSysId>"); // sys_id of the record which you will be creating for scheduled import in step (a)
exportGr.query();
if (exportGr.next()) {
gs.executeNow(exportGr); // this is for scoped app
// SncTriggerSynchronizer.executeNow(schImp_GR); // this is for non scoped app
}
