Hello,
I am trying to add a value to a lookup field on a CRM phone, via C# code.
The lookup field value already exists - I just want to populate the CRM form field (linked to the lookup) with this value.
The lookup is a custom entity with just one field and I know the value of the field but not the GUID.
Does anyone know how I can add it without knowing the GUID, using something like EntityReference??
Many thanks,
