Finding actual receve from multiple records

Hi,

I have 2 tables that contains the received transaction. the first table is a header and the other table is a details. if you see the details table there are source type named inventory and purchase. Purchase is the actual receive in Warehouse while Inventory was named after there was an adjustment. I would like to get the if there's an adjustment made or a regular receiving only. Thank you

create table  #sample_header
(id nvarchar(50), [type] int , itemid nvarchar(50),  createddatetime datetime, modified_date datetime, sourceid int)
insert into #sample_header
select '18987174400',2,'MAL123456RGD','2017-01-22 23:44:11.000','2017-02-15 16:06:25.000',3

select h.id, d.itemid, d.type_source, d.createddatetime, d.modified_date, d.[source]
from	#sample_header h
		inner join #sample_details d 
		on h.id = d.id


desired result:
id---------itemid--------type_source----createddatetime-----modified_date---------source
