Error while obtaining JCO connection.

[Former Member]

Hi I'm trying to put in place since BW-SEM RSPLAN the transaction, I'm pointing at my portal from the transaction RSPLSA

But when it signs the user gets the message Error while obtaining JCO connection.

I was reviewing my WebDynpro on my site by following these steps:

1 I will http://portal:port

2 I clicked Webdynpro

3 I click on Content Administrator

I clicked on 4 Maintain JCO destinations

and then I log shows the following:

Failed to process request. Please contact your system administrator.

Hi Antonio,

Follow the below note for Jco related troubleshooting.

https://service.sap.com/sap/support/notes/919850

Are you able to see the 4 Jco connections green?

Debasis.
