Hi
In material master costing 2 view we have two different fields i.e. Planned price (LPLPR) and Standard price (STPRS). Planned price field is updated with the cost calculated during standard cost estimate (CK11N/CK40N) and at the same time standard price field is also updated with the same cost.
Whereas standard price field can also be updated through other ways (MR21). But if you give price through MR21 it can not be updated to planned price field. This is the reason when you do CKR1 (re-organization of cost) system only reorganizes planned price field and price at standard price field remains the same. This is because all material movements happen in system with standard price field.
This was a general understanding on these two fields where you are stuck up. Now coming to your today's Q1 : If you have stock in the material and you don't give any price with CK40N/CK11N or MR21 then the stock will be valuated with ZERO price hence fetching value.
Q2: CK11N is done with quantity structure means using BOM and Routings. Till these two are not changed either in terms of quantity or price, system will calculate same standard price (in your case 119000), even you do it 100 times. And as I said in above paras the same price will be updated in standard price field also hence 200 can not remain there.
