Hi guys,

i have a requirement i need to update child record from the parent context using custom workflow.

I used below code but throwing an error "given key was not present in the dictionary".

should i use any arguments to achieve this?

try
{
Entity entity = new Entity();
entity.LogicalName = "tj_country";
EntityReference child = (EntityReference)entity.Attributes["tj_child"];
Guid cid = child.Id;
Entity childentity = new Entity();
childentity.LogicalName = "tj_state";
childentity.Id = cid;
childentity.Attributes["tj_districts"] = new OptionSetValue(212200000);
service.Update(childentity);

}

Validate you entity fields logical name. "given key was not present in the dictionary" error occurs when no field with specified logical name is found in CRM for particular entity

Hi,

when you are creating that entity in the code, it's just an in-memory object - not a record from the database.

Hence, it does not have tj_child attribute until you set it..

Instead, you have to use Retrieve to get that entity from the db.. Something like this:

var entity = Service.Retrieve(context.PrimaryEntityName, context.PrimaryEntityId, new ColumnSet("tj_child");

Hi,

Please check if logical names of fields "tj_country","tj_child","tj_state" and ""tj_districts"" are same as defined in CRM.

This error generally occurs when no field with specified logical name is found in CRM.

Hope This Helps!

Thanks

Hi,

Instead of the childentity.Attributes ["tj_districts"] = new OptionSetValue (212200000) try to use childentity.Attributes.Add ("tj_districts", new OptionSetValue (212200000));

Or you can remove the word Attributes something like this hildentity ["tj_districts"] = new OptionSetValue (212200000);

Hope this helps
