Copy field content from one entity to another

[roxt]

Hi,
I created a new entity and would like to copy the field from an existing entity to it: E.g. using Quotes>Quote Number and copy it to the new entity Invoices> Quote Number.

I tried the following: I created a link between Quotes and Invoices and created a field "number" in Invoices of similar type as in Quotes (number, Quote Number, varchar). Then I added this field in the Layout Manager to the List and Detail views of Invoices. However, by creating a new Invoice from an existing Quote, the field Quote Number is not copied. What is my mistake?

Thank you very much!

Hi,
What is the field type using for Invoice Quote Number field?

Hi,
it is the same as for the Quote entity: Varchar.

Thanks

How did you try to copy this field? Maybe foreign field will be enough
