Index error

Hi

I am trying to delete a batch of old jobs.  I have grouped them under a header job and understand that by deleting the header job all the sub jobs should delete.

However, my MYOB keeps kicking me out and previous requests for assistance point to an indexing error.

I cannot get any direction on how to fix an indexing error.

How can I fix an indexing issue?

Does MYOB offer a service to delete unwanted data from my file?

Does MYOB offer a service to fix indexing issues?

Can you recommend an app/service/add on which will delete old unwanted jobs?  Jobs which have an indexing error.

Thanks
