Hi ,

I need to fetch the value of one entity to another entity on create screen itself

For example :

I have Quote and Invoice entity

we can create invoice against a quote , during creation time i need to fetch the value of quote number initially when the create fields are loaded in the invoice page.

Foreign Field mapping shows empty value - EspoCRM Open Source Community Forum

https://forum.espocrm.com/forum/developer-help/50144-foreign-field-mapping-shows-empty-value

I have 2 entities 1. Quote (it has One-to-Many relationship with install) 2. Install ( it has Many-to-One relationship with quote ) in install section i try to get data of Quote , so for example i mapped Date quoted in the install section. I added the foreign fields in the install section having link with the Quote ,

I already posted this question here and Maximus gave me a example on how to fetch , but it works only after submitting the form.

I need the value to be displayed on create screen before save itself.
