SPROXY

Hi All:

I am configuring the tcode: sproxy in R/3 but there is not connection with the integration builder, the table sproxet has got an entry:

IFR_ADDRESS http://gestsapxid.sap.gestamp.com:50000/rep

But the report SPROX_CHECK_IFR_RESPONSE is getting an error:

"Integration Builder data not understood" .

I do not know if this is a problem with the Exchange profile, How Can I access to the R/3 Exchange profile?

Thx
