Hi Bärbel.
Why not doing this in an object trigger ?
POST_VALIDATE for example.
assuming ci_stellplatz_nr is your incident Attribute the Code might look like
(majic) MODIFY cr POST_VALIDATE your_trigger() 110;
spel
cr::your_trigger(...) {
ci_stellplatz_nr=affected_resource.zTA_Stellplatz_Nr;
}
Where and how exactly do you need the new attribute value in your remote reference. If you use a ci_stellplatz_nr substitution in your remote refernence definition, you might be able to use "affected_resource.zTA_:Stellplatz_Nr" instead. So you could prevent any additional change.
cdtj What is meant by "2) I really need it". Are you looking for a solution getting some values by ajax based on changes of affected_resource?
Best regards
