Posted on by Mani_ratname

Hi Team, (using Dynamics 365 Crm, Visual Studio 2017)

I have two entity Account and B(Custom entity). and In the entity B has one lookup field (For this lookup field target entity is Account) ,Based on the selection of lookup field ; the other field of entity B should be populate (ie. If I select any Account which one has some field a1,a2 then respectively value should come for field b1,b2 in entity B1). I want to do this "using Plugin".

So, Please help me regarding this, i am new in Crm. Basically , i need business logic code for plugin.

Thanks.

Instead of writing code in a plugin, you could do this with a workflow that is triggered on update of the lookup field on entity B, and updates entity B with the values from record A

Hi

You can do this using plugin but there are other ways to achieve this.

You can create a workflow that triggers on the lookup field change and copies value from Account to fields on Entity B.

Let us know if you still have to do this using plugin.

Also let us know if you need any help in doing this via workflow

Entity CustomEntity =context.Inputparameters["Target"] as Entity;

Entityreference Account =CustomEntity.getAttributevalue<EntityReference>("Account");

Entity Account=service.retrive("Account",Account.id, new columnSet("field b1", "field b2") );

//in your logic you can use it

Customentity["field a1"] = Account["field b1"];

Customentity["field a2"] = Account["field b2"];

//after complete register the plugin in "pre operation"

Hi Mani_ratname,

In your situation you can use pre operation plugin. Please refer following code for reference:

Entity _entity = (Entity)context.InputParameters["Target"];

Guid LookupId = _entity.Attributes.Contains("lookupname") ? _entity.GetAttributeValue<EntityReference>("lookupname").Id : Guid.Empty;

Entity EntityDate = service.Retrieve("entitylogicalname", LookupId, new ColumnSet(true);

_entity.Attributes["attributelogicalname"] = //Pass value here;

_entity.Attributes["attributelogicalname"] = //Pass value here;

_entity.Attributes["attributelogicalname"] = //Pass value here;

context.InputParameters["Target"] = _entity;
