deactivate phrases

Hi all,

I would like to deactivate a list of phrase keys. I was thinking I could do this via the phrase import DAT file. I thought I could add a line for the "VALTO" field. as follows:

+EV

+BV   $ESTPH

PHRID                          12345678

SRLANGU                        E

VALTO       31.01.2014

+EV

When I import the file, it complains that :

So it seems that the phrase import program does not recognize all of the fields available in ESTPH? Is there a limitation on the fields one can put in the DAT file?

Any other ideas how to do this?

thanks,

Scott
