Before you load records, you might wish to run a test to see what the result will be, for example, whether a record will be loaded as new or whether it will replace an existing record.
To test an upload:
The Uploading Records dialog is displayed, showing all the possible load statuses are listed (from 0 to 10). The statuses which are used in the test load will depend on the load control parameters.
The results of the test are shown in the Status column. “T” means that the status is from a test load. (“L” would mean that the status is from a load.)
You might want to sort the records at this point to bring together the ones with similar statuses/errors. Click on the heading of the column you wish to sort by.
