RE: Plugin Problem

Hello,

As per the below line, I can see syntax error.

entity.Attributes["kbitsol_name"] = prefix + finalrecord;

it should be

entity["kbitsol_name"] = prefix + finalrecord; // preferred - override if there is an existing attributes in entity

or

entity.Attributes.Add["kbitsol_name"] = prefix + finalrecord; // in case you are adding new filed to entity attributes list

Since, you haven't used "service.update" I believe it is been triggered on Pre-Create of your target entity. Otherwise you cannot see the update.

Hi,

It seems like connection with crm is not created. "Object reference does not have an instance of object". Try to throw an exception in code.

Hope it helps.

Thanks
