It appears that the Master text / Source Text is linked to the Notes or Text field in FSFT.
When you attach a source in FSFT through the automatic linking routine, the Notes or Text field is not available to enter data. Only the Reason Statement is available. So, if you use that field and then transfer a source to RM, that information is lost.
Is there a field in RM that links to the Reason Statement field in FSFT. That would be the ideal linkage for me.
