Parental Relationship

Account --> Entity A

Referential Relationship

Entity B -- Account

Entity B -- Entity A

With simple JavaScript, when a user selects the lookup value for the account, the lookup for Entity A can be filtered to point to only those entity A's that are related to the account you just chose. Here's the code to place on the form of Entity B:

crmForm.all.<lookup field for entity A>.additionalparams = 'search=' + encodeURIComponent(crmForm.all.<lookup field for account>.DataValue[0].name);

That's it! Simple, yet effective.

Что этот пример делает? можно ли с помощью его фильтровать продукты в формах?
