    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

    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.
