AX 2012 - If batch jobs cannot start?

If you look up Home->Inquiries->Batch jobs->My batch jobs and see batch jobs don't start.

Go System administration->Setup->System->Server configuration and check there is a record at Batch server schedule with proper time gap (00:00 -23:59) and be careful about Maximum batch threads value bigger than zero.

Also problem maybe about there is no attached server to batch group :
Administration -> setup -> Batch Groups
Find empty batch group and go Batch Servers tab, look for Selected server field has correct server value.

AX 2012 - Refresh form data

A Subroutine of you called refreshs data. Form's data doesn't refresh. To solve this issue you have to call first research and then refresh. Research doesn't broke your query filters and if you call it with true parameter it goes to current record after refresh:

    LedgerJournalTrans_DS.research(true);
    LedgerJournalTrans_DS.refresh();

If your subroutine is a SysOperation class and your screen doesn't refresh anyway, don't forget add this to your controller class:

 controller.parmExecutionMode(SysOperationExecutionMode::Asynchronous);

If you don't, your research and refresh methods run before your classes completed it's job.

AX 2012 - Sysoperation class sample

Contract Class:
classDeclaration method:
