com.sap.mw.jco.JCO$Exception: (101) RFC_ERROR_PROGRAM: 'password' missing

162 Views

Hi gurus,

I have a problem about ESS. I have configured the ESS and it was working absolutely without a problem.

But this morning I faced a surprise. When I try to enter the iviews of ESS, I get the following error about JCOs.:

The initial exception that caused the request to fail, was:

com.sap.mw.jco.JCO$Exception: (101) RFC_ERROR_PROGRAM: 'password' missing

at com.sap.mw.jco.MiddlewareJRfc.generateJCoException(MiddlewareJRfc.java:457)

at com.sap.mw.jco.MiddlewareJRfc$Client.connect(MiddlewareJRfc.java:1015)

... 55 more

I have maintained the JCOs again and authentication method at JCOs is Ticket. No problem with pings.

Any suggestions....

Best and kindest regards

Tolga
