Error Subscription from SMP 3.0

Hello,

When I send subscription from native Android app (using SMP SDK), that is registred on SMP 3.0, Gateway receive error "Internal Server Error".

I debug Gateway code and I find the error reason, method /IWBEP/CL_MGW_PUSH_ABS_DATA->CREATE_SUBSCRIPTION line 96, check atribut 'request_user'. This atribut is missing in parameters application context.

If I send same subscription direct to Gateway it works, and subscription saved! Parametr 'request_user' is filled by my username...

Could anybody know how set this parameter? Or if SAP release note, that fix this problem?

I used SMP server 3.0 SP 4, Standallone Gateway 2.0 SP 06 ( SAP_GWFND 7.4 SP6)

Thanks

Jan
