HWC - Process Online-Request's results from multiple queries

Hi Experts.

I'm new at SAP.

We are using SUP 2.2 SP04.

We created an application that uses online request (MBO objective query) and works on HWC .

We could call query and process incoming data in such a way that at the following URL : SyBooks Online .

But we have a problem when client receives two or more results almost at the same time - The results from query which received in advance vanish.

For example,we receive results from query1(receive results in advance) and query2(receive results later) almost at the same time ,and results from query1 are vanished.

Now we're deal with this problem by generating the waiting time by the synchronization process.

Are there any solutions?

Thank you in advance.
