I have a customer with major issues in MAS 90. On the MAS server, the RAID controller failed causing the drive to go wonky. That was fixed, but now they can't do things in MAS 90, specifically related to the Sales Order module. They get SO_SalesOrder_bus not found and SO_Invoice_bus not found. I reinstalled MAS 90, all product updates, etc. (This is 4.30 SU18.) It was still happening.
Then I try an old test company and I can get in, no errors. I copy the main company to a test company and I get errors in the test company. This makes me think it's something with the data files. I rebuild all of SO files, it corrects a couple files but still can't get in. I try to rebuild sorts for SO and get error 112 SOZUZA line 0143. Nothing on KB.
I try to shut down custom screens with *esc and that doesn't work. I rebuild all CI files, that doesn't work. I rebuild all GL files, that doesn't work. I compare the list of data files from the company code that works to the one that doesn't and the number of files is the same.
