We have reached a problem here in an interface concerning SAP and an external system.
I will try to make a description of what's happening.
I made some RFC functions to be called by another external non-sap system to extract data from SAP. The linkage is made using Webservices (SOAP). We came across an error of TIMEOUT. If I execute the function directly from SAP(SE37) the information is extracted perfectly, but if the other system tries to call the function, they get an TimeOut , The error they get is "The request failed with HTTP status 504: Gateway Time-Out.", we've changed the timeout time in SAP to 15 minutes, but this doesn't solve the problem, they keep getting the error.
Does anyone know what might be wrong ?
One funny thing is that this occurs just with 2 of the interfaces, the others work well, but these two keep getting this error.
