I have a CRM Form, with 2 fields.
I need to automatically populate the second field with data returned from a different system, based on the value that the user keys into the first field.
I have a web service that accepts a text value, then goes out and runs a query against the external system and returns a value.
What I need to understand "how to do" is when the user keys in a value in new_casenum field on the CRM Form, I need CRM to call that the web service on change and whatever the web service returns needs to somehow go in the new_casenum field on the form, the user will then continue to enter data on the rest of the form before saving it.
I am not worried about error handling yet, I just need to get this concept down and get something very basic working so I can build up from there.
Can anyone who has done something like this offer some guidance as to how something like this can be done?
