16a equity method,the investment is loss the positon came to zero

Question

Hi,experts
We have trouble when our investment is came to zero,with equity method.
In China GAAP ,The real business backgroud is our investment is equity method,not cost
method.
every year we will get the corporation 's profit or loss .And we shall
count it decrease or increase at our hold percent.
If we investment 10000,and the company
profit 1000 ,our holding is 20% the we will increase our positon by 200
If loss ,then we decrease 200 position.
Use tpm12,we shall see the position now is 10000 +- 200.
We can't use sell and buy because there is not real sell or buy happend
and no bank pay or received at all.
We use FWZZ add the condition set up by our consultant just as bonus condition type.
and the position change category should be different (1005),
if the reduse amount is not as the position,there is not problem.
But when it is reduce the  same   amount as the position .Errors cames out.
When saved it .There will be no flow came out at all.
SAP SUPPORT TOLD :you need to use FTR_CREATE and a flow like se2000 sell it  to finish the business.
Did you know the more standard mehthod of euqity method yearly euqity increase ore decrease?
Thanks and  best regards.

Not exactly sure what is being accomplished, but your problem lies with the setData method (as stated by the trace).
When calling the method, you are doing myUse.setData(21, c) or myUse.setData(248, c). In both cases, you are passing two arguments (21 and c or 248 and c). However, the method setData() in the UseDataClass is not setup to accept any arguements. You need to do one of the following:
1) if you want to use the two numbers being passed, you need to change the method to be something like:
//up top:
myUse.setData(21,c);
//within the UseDataClass class:
setData(int a, int b)
//then do whatever you want to with the a and b...for instance:
t = a;
co = b;
//now t =21 and co = c
2) if you don't want to use any of the numbers being passed, then don't pass them:
//up top:
myUse.setData();
//you can just leave the setData() method alone since it is already setup to work without arguements
3) If you want to switch between the two methods (ie - sometimes pass arguements and sometimes not), you can create another method like the one in the first example.
here's what I mean:
class UseDataClass
public void setData()
//do what ever you want here without worrying about any values...
public void setData(int a, int b)
//now use the a and b values...
You could then do either:
myUse.setData();
or
myUse.setData(21, c);
