Diagnosis
You set the American date format (MM/DD/YYYY) for the Excel legacy datatransfer. (If you did not make a setting, the setting was adopted fromyour user master record.)
However, the value of the '&v1&' field, which was transferred from thetransfer file, contains a period (.). This seems to indicate theEuropean date format (DD.MM.YYYY).

System Response
This is only a warning. In an update run, the system creates the assetmaster record and interprets the transferred value in the unusual formatMM.DD.YYYY, as an exception.

Procedure
Check your input file. If you want the date to be interpreted using thisunusual MM.DD.YYYY format, you do not have to do anything.
However, if you want the date to be transferred in DD.MM.YYYY format,check if all the dates in the input file are in this format. If so, thenchange the date format from the menu. Choose Settings -> Dateformat.
If your input file contains some dates in DD.MM.YYYY format and othersin MM/DD/YYYY format, you have to change your input file so that alldates are in either American format or European format.
