Problem

Update fields do not get updated properly when plotting from Print Organizer and Batch plot. 

Solution

Make sure the following MS variables are set:
MS_PLT_UPDATE_FIELDS=1
MS_AUTO_UPDATE_FIELDS=ALWAYS

In addition, the file must be opened Read/Write by the plotting interface.

For Print Organizer, set:
MS_PRINTORGANIZER_OPEN_DGN_READWRITE=1

For Batch plot, set:
MS_BATCHPRINT_NO_READONLY = 1
