In Library Master - Setup - System Configuration on the Security tab make sure the option in the SData section "Enable Native SData Provider and Access within Role Maintenance" is selected.

Thanks Kent. This is enabled.

Sage support suggested uninstalling Sage100 v2016 and reinstalling SData v2013.

The message you are getting should only display if this setting is not enabled. Double check the setting in Data File Display and Maintenance to be sure. Run Data File Display and Maintenance. Enter "SY_SYSTEM.M4T" as the table name. Find the "EnableNativeSDataProvider$" column and make sure it is set to "Y".

If it is not set to "Y", edit the column value and make it "Y" then try SData again.

If it is set to "Y" and you are still having the issue, then it is possible that one or more programs may be corrupt. Please ask Customer Support to work with you to replace the SY_SDDataServer.pvc and/or SY_SDataSystem.pvc programs in your installation.

Thanks Kent! I'll give these a try and report back.

Worked with Sage support for a few days on this. The 2016 install messed with some dlls that could not get republished by a reinstall of 2013. Brian had to manually fix entries with regedit. Lesson learned: Don't install test versions of Sage100 Advanced on the same server as the working version.
