Hi Seniors ,

I tried to create JCO connection from EP to ECC system and it showed an error message as shown below.

Exception while creating JCo client connection Failed to create new JCO client connection SAP_R3_HumanResources_MetaData: com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscapeException: Connection SAP_R3_HumanResources_MetaData already exists in the SLD.

Hello,

Log is showing that this JCO is already there "Connection SAP_R3_HumanResources_MetaData already exists in the SLD". Please first check the available JCO connection if it is there then delete it and recreate it.
