I'm not sure that I understand your question completely, but I think that you want a weighted average of variables from two observations to be put into a single observation. If so, -collapse- provides a way.
*************CODE BEGINS*************
sysuse auto, clear
keep in 1/2
drop make
gen part = _n //
label define part 1 "West" 2 "East"
label values part part
list mpg weight length trunk part
gen myweight = 1.23 if part==1
replace myweight= 0.55 if part==2
collapse mpg weight length trunk [pw =myweight]
gen country ="Germany"
list
**************CODE ENDS**************
By the way, "STATA" is not correct spelling of the program we all use, but "Stata" is. See the end of the Statalist FAQ for the reason.

Dear statlisters,
I create a variable "Germany" but when the whole country is taken as
the unit of analysis (rather than eastern and western states), a
design weight is necessary: weighting factor for Western Germany:
1,23; weighting factor for Eastern Germany: 0,55.
As the help weight command did not solve my problem, I would be v.
thankful if someone could tell me how to code that in STATA. Many
thanks, David
