How to set a Batch name at Import Level (Import Processor)?

Hi,

I am trying to set the batch name at the import level in Oracle webcentre Capture Version 12.1.1 , so to achieve that i have written the below script , Script seems to be working fine as i am getting the output at console (like batchname etc) But when i am trying to set the batch name using  batch.setBatchName(mBatchName) it's not changing the batch name.

And i am also not getting any exception or so at backend.

Can someone please look into this and guide if i am doing it correctly?

var batch;

var logger;

var mBatchName;

function postImportFile(ctx) { // ImportProcessorContext
