将数据从外部数据库绑定到 MS Dynamics CRM 子网格

Question

I am not able to set lookup fields on MSCRM sub grid from external database.

I tried with the retrieve multiple plugin as:

get the data from external database in datatable

EntityCollection entityCollection= (EntityCollection)context.OutputParameters["BusinessEntityCollection"];
Entity anyEntity= new Entity("entity");

anyEntity.Attributes["new_customerid"] = new EntityReference("contact", new Guid("B26EF3E7-BD68-E411-9447-00155D010B06"));
anyEntity.Attributes["new_address1"] ="value from datatable";

entityCollection.Entities.Add(anyEntity);

Except lookup type field I am able to bind all the fields to the sub grid from external database.

This is expected since you cannot "look up" to a record in a different database. CRM enforces foreign key constraints on lookup fields so that you can only set a lookup value to point to an entity that actually exists in that CRM system. You could however set the lookup to a value in CRM based on some value in the other database.
