RE: How to set a value in a custom field and increment by 1 each time the new record is created.
Hi Sandy Hello how are you?
Yes, you can do that. But think that you have to create the structure to save the number, the next number, prefix and suffix.
You can use a plug-in using the SDK and samples on it to retrieve the configuration from this entity and on the pre create add the counter. Using java script is the same approach. You have to query this entity, create the number and add it on the attribute on form.
I think that this is not so easy as the Auto Number plug-in and the Dynamics platform will increment and create the value to you.
