Change Metadata JCO in Webdynpro application

Question

Hello all,
I am trying to change the metadata jco destination in a webdynpro application.
Although I have changed this in property "logical system name" of the dictionary, I am getting this error when I run the application :
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name "OLD_JCO" in the SLD. No such JCO destination is defined in the SLD.
<b>The JCo destination seems to be pointing to the old jco (which does not exist anymore).</b>
I have changed the JCo destinations for many applications earlier but had never faced this problem. For some reason, one application is giving this error.
Is there any other place that needs to be updated with the new JCo destination?
Thanks and Regards,
Reena

Hi Suresh,
The Metadata JCo destination that is mentioned in the error message does not exist. I am aware of this and this JCo was deletd deliberately as we did not need it. In place of this, we created two new JCos and also changed our Wen Dynpro programs to reflect the new JCos. Two WD applications succesfully recognized the new JCos and are working well.
However, the third WD project, is still pointing to the old JCos that we had deleted.
We do not want to create these old JCos again.
Here is the error description:
The initial exception that caused the request to fail, was:
