Hello,
is there a (not custom code) way to pass the values of an existing entity record to a new lookup form?
Case:
In the entity salesorder exists this lookup to the entity sc-data

Problem:
If the user clicks on "Neu" (New) it should automatically fill-out some fields that are already filled out in the salesorder.
My ideas:
- If possible: Get parent id from the Xrm context and retrieve the data. Then use Xrm setValue.
- Create a custom button and HTML
- Using Business process flow (I could not achive it with that. Since I could not create an entity with it or pass parameters to the workflow that should create the new entity.)
- Field mappings. It seems like that it did not work, because it is a N:1 relationship.
Any suggestions?
