Update cross reference in batch job - AX 2012 R2, R3

Below is the code snippets to update cross references of all AOT objects through batch job.

static void UpdateCrossRefBatch(Args _args)
{
   ;
   xRefUpdate::truncateXrefTables();
   xRefUpdateIL::updateAllXref(true, false, true);
   info("Done, cross reference update batch job created.");
}

Batch job will get added with the description as "Update xref for complete AOT" .

Happy Daxing !!
