Dear John
there is the "Easy Expert" available as well. But this is used more rarely as the Expert server rules, as the rules muts be much simpler.
What you would try to get is something there i would not use the term "rule" but on high level it is a rule clearly. You have this option: prepare your owen "secondary determination "program" " to do the job. Do it in ABAP. Secondary data determination and "output variant" is on the "same" level. First you read some data. Secondary data determination is the related to "create" new data (as in your example) and output variants are used only to show the data on the screen.
As with many rules: the "copy" one is tricky (therefore many people have some problem in using e.G. Content Provider data; here you have a "similar" process. Here you import (insert but update and delete as well) data. Regarindg your topic. it depends what you would like tot achieve.
E.g. you have a data record fomr property X; now you copy that to the same "VAT" (using only different usage) or you generate a new property Y with the sam structure as X and copy th data viy Scondara determination" option. The only topic you need to think about: how should the update be done in Y (if there is the need to do so), as you always need to consider thre options.
- insert new data
- use some VAT but update that
- delete the VAT
What should now happen in case of "deletion" ? Do you would like still to "copy"?
