Could not create JCOClientConnection for logical System: WD_MODELDATA_DEST - Model: class com.sap.sap.bapi2.model.Model_enquiry. Please assure that you have configured the RFC connections and/or logical system name properly for this model!

some time back it was working fine.

Hi Sarbjeet,

Check the JCo Pool Configuration settings of your JCO Destination. This message normally comes when the maximum connections has been reached. Increase the "Maximum Connections" to some number depending on the usage. A good habit is to disconnect the jco connection after executing the same in your webdynpro code if you don't want it to be synchronous.

<ModelName>.modelInstance().disconnectIfAlive()

Hope this helps.

Regards

Narendra
