Today I was trying MfgApps Import/Export functionality and found out that importing the same file that was exported (no modification) makes the import process to skip almost all the rows from the properties tab.
Viewing the logs:
Import Validation Process: [Properties Tab] [Equipment Name: Asset_LocallyBoundAsset][Name: statusTimestamp] Invalid reason: Changing Base Type is not supported
but I haven't changed anything to the file.
The expected behavior is that all 159 be marked as valid (instead of 7 valid, and 152 invalid).
I recommend that a case be opened for this issue. With your approval, I will be happy to open it on your behalf.
