What version are you running?

What happens if you try to create a different test company (say ZZA)?

Have you previously had a company ZZZ in this installation? Possibly there are some left over orphaned files/settings?

If you look in your MAS90 folder for MAS_ZZZ, do you see any folders for modules that you don't believe you have activated? (For example, there might be an APZZZ folder)?

Do you have any third party modifications?

This is from the knowledgebase.

Cause


•This error is caused by the installed modifications. The master developer who created the enhancement should be contacted to report the issue.


•Anti-virus scanning MAS90 folder during conversion





Resolution


Look for ".Not Setup" folders in the Data Directory:

1.Open File, Run and type in *Info


2.Click OK


3.Browse to the \MAS90 folder listed here via Windows Explorer or Start, Run in Windows


4.Rename any ".Not Setup" Folders and their matching XXyyy folder


5.After renaming each one, go to Modules, Library Master, Company Maintenance


6.Select the affected Company Code


7.Click "Activate"


8.If the Message "Data files must be converted" appears, then the module that was renamed is not the cause


9.Repeat this procedure until the "Activate" dialog comes back by renaming in this order:

◦.Not Setup Folders


◦Modules that are not setup but appear in the MAS_xxx folder


◦3rd Party Modifications


◦Legacy Modules



10.Once the activation screen appears (see below screenshot), the last renamed module is the cause of the error message. Rename each folder back one by one, each time repeating the "Activate/Cancel" procedure in Company Maintenance


11.If the module causing the error is a 3rd party module, contact the Developer responsible for the modification for instructions on how to proceed


12.Consult the Installed Modules Listing under Library Master, Reports in order to determine the developer responsible for the modification(s).


13.In a few isolated incidents, this message has been caused by a Legacy module that was setup but not used.


NOTE: Do not click the "ACTIVATE" button in a live company as this will create new data files











If the issue persists:
1.Copy the MAS_SYSTEM\SY_EnhancementModule.M4T file to a directory outside of the MAS 90 directory.
2.Expand Modules, Library Master, and Utilities. Double-click Data File Display and Maintenance.
3.In the File Name field, select the SY_EnhancementModule.M4T file.
4.Click the Delete button to delete all records in this file one by one.
5.Rename the ...\MAS 90\Links folder.
6.Create a temporary Links folder and copy the default.pvc file from the old Links folder.
7.Proceed with the copy or activation process.
8.Delete the temporary Links folder, and rename the original Links folder (to Links in the \MAS 90\ directory).
9.Delete the ...\MAS_SYSTEM\SY_EnhancementModule.M4T file and restore the original file (from the backup created in previous steps).



•Disable Anti-Virus


•Run Conversion from Sage 100 ERP Server

I gave up and deleted the company and started again. Stupid errors like these frustrate me with Sage 100.

I will conur that they can be frustrating. If everyone's environment were the same, there would probably be a lot less of these things, Unfortunately everyone having identical environments probably ain't gonna happen. ;)
