[LDM #GZE-935760]: Reassigning LDM feedtype

Hi Carrie,

No, this is not possible.  Moreover, the product extracted (written, etc.)
from the queue would have to change in order for a re-insertion to work.
If the product is not changed, the MD5 signature will remain the same, and
the duplicate product detection inherent in the system would reject the

OK, I understand the desire to change feed type.  I don't understand why
some users are unhappy with the feedtype that is being used.  This should
all be transparent to the end user.

Yes.  When the product is extracted, slightly changed and then re-inserted
you can specify more than one feedtype.  Please note that this would be a
bad idea IF the machines participating in the data exchange start interacting
with machines that are participating in the IDD.

No worries.
