The export records script step does support the partial export of data. In the options dialog for the script step there is an "specify field order" option where you can specify exactly which fields export.
thank you for your answer, but it seems like I asked the question wrong. I don't want to export a row, i only want to copy/export one specific field into another table on another pc. every entry has its own ID and If this ID isnt listed there, a new entry will be created. I know you can accomplish this with the export/import script in only one step, but this isnt what i want to do. I only want to copy one single field
You do not understand the solution proposed by Mike B.
Export allows you to choose the columns (fields) and exports all the rows in the found set for the chosen columns/fields.
If you choose one field/col it will export all rows in the found set for that single field/col.
if you want to export only one row/col then, before you do the export isolate the one row you want to extract with a find.
Is that not exactly what you asked for?
Oh sorry! it seems like the answer was actually right but i'm new at filemaker and cant speak english perfect so i think this is why i didn't got the first answer. thanks you very much for explaining it further to me! I will ask again when i need help, you guys are awesome!
