Control of serial numbers in productions (parts and final product serials)

Question

Hi,
We are starting using our production module in SBO 9.0 PL11 and it is all quite messy.
We need to manufacture an item that has a serial number made of parts, some of which have serial numbers. Just imagine a car. The car will have its own serial number, but the engine, the radio and so on will have their own serial numbers. But the cables, tyres, etc do not have  a serial of their own.
We set a BOM model, made of every part (with or without serial) and set every line to manual.
Then we place a PO for our parts, and then do a Goods Receipt and enter the individual items' serials.
Then, we issue a Production order for our final product made of all of our parts in the BOM. Then we release it for production.
Next, it all gets messi. If we create a receipt from production, we can issue the serial number of each of our final products.
If we create an Issue for Production, we can choose what serials to pick for production.
Big problem is that we loose all traceability. There is no way (or we can't find it) to know what are the serials of the parts that created the final product.
Not only this, issue for production looks (serial number transaction report-wise) looks like a goods issue, so just a way to decrease your parts stock. And receipt of production looks like a goods receipt. So you just now you received something for production or that you issued it to production, but there doesn't seem to be a link between them. No traceability at all.
Can anyone throw some light into this? I am sure we are doing something really wrong, but can't see what.

Hi,
1. But how do we control what serial numbers for each part we used to create the final product specific serial? (I use engine #003 and radio #376) to create product with serial #076. And we always produce in quantities greater than 1.
Please provide an sample process production with FG item and components with required serial format to check
2. This query is not returning any rows. I am inputing a final product code, with production orders, and nothing shows up.
As mentioned, the above query works for batch managed items. Once we conclude process, I can try modify above query to meet your purpose.
3. It sounds really complicated to have to open both receipt and issue to track a single manufacturing operation.
You can use relationship map option to view both issue and receipt for single production.
4. Besides that, what is the exact workflow? I don't quite understand issue and receipt, should I run both independently?
Standard work flow for production order:
1. Create bill of material
2. Create planned production order based on above BOM
3. Make sure required components are arrived.
4. Change planned to released status.
5. Issue components to production by issue production
6. Receive finished item from production through receipt from production.
