Now if you want to import the custom fields of others catalogs, then use import/export in custom fields manager. Import will not remove your own catalog fields, just add missing fields or change properties if are differents .
hm, not so for me.
If I import the fields from catalog 2 (which I have exported before) in catalog 1 then
case 1 - the new fields are imported while the actual are deleted.
case 2 - no fields are imported.
For example, I created a field called "VHS" (Boolean) in catalog 1 and a field called "DVD" (string) in catalog 2 which I export in each case. When I import VHS.xml in cat 2 then filed DVD is vanishing, when I import "DVD" in cat 1 nothing happens.
---EDIT
I have to correct me. Both fields are there in both cases but one was not seen until I moved the field! You have to ensure that they are not at the same position, otherwise one field will be "overwritten" on the monitor. "VHS" then is always in foreground.
==> The way it works:
1) export fields from cat 2
2) import exported fields from cat 2 in cat 1
3) import cat 2 in cat 1
4) ensure right position of imported fields

- perhaps by "default positioning for new fields"
OK it works, but seems to be a bit complicate to me, I would not have solved this witout your hint. Couldn´t it be automaticly imported from cat 2 and (maybe) positioned "below" the actual fields?
... then your job is to match fields from other catalog to your own catalog fields (click on header column to choose field).
Wouldn´t it be nice to choose the new custom fields to import while importing the catalog itself? Instead of trying to match the fields I rather would like to choose which new/imported field I like to add.
--- EDIT 2
After trying this for different situations I have to say it is not a big trouble the way it works now. But perhaps it´s a good idea to give a hint in the help file for this little import process (the 4 steps from above).
