Hey everyone.
i have a problem with the SAP set/get parameters - and i can't solve it on my own.
I have a report, that submits another report in a loop ( please dont ask why 
)
The second report creates a URL based on some information and sends a request to a server, based on the class cl_http_client.
the URL has a parameter called "timestamp" that has to have a constant value.
Which means, for every submit in the loop i want the same timestamp.
i use the following syntax to set the parameter:
* declaration
data: lv_parameter_value type memoryid.
* body
clear lv_parameter_value.
get parameter id 'PARAMETER' field lv_parameter_value.
if lv_parameter_value is not initial.
gv_timestamp = lv_parameter_value.
rv_timestamp = gv_timestamp.
else.
get time stamp field rv_timestamp.
lv_parameter_value = rv_timestamp.
set parameter id 'PARAMETER' field lv_parameter_value.
endif.
The problem is: AFTER the call of "receive" of my cl_http_client-instance, the Parameter gets cleared...
So in the following call of the coding lv_parameter_value is empty.
i have created a report for test purposes, that doesnt include the http-client.. just to verify the SPA/GPA-parameters work within a loop and a submit statement. Without the call of receive it works 
Might there be a bug? a OSS Note for my problem?
Thanks for your responses!
Regards,
Pascal
