MRP Generation runs forever, no error messages

I am trying to run an MRP generation to generate a report.  I am doing so in the legacy MRP for Sage 100 ERP version 2018.  This will be the first time that the generation would be run for this particular company.  The files for this company are not gigantic, but the MRP generation was not complete after generating for more than 36 hours.  No errors appeared, but no error messages came up either.

I am wondering what diagnostic steps could be run to identify the problem.  Hopefully the diagnostics would also identify potential solutions as well.

Thanks in advance.
