Technical Details :
Version : EP 7.01 SP8 .
Error Screenshots :
1. BW Reports loading issue :
When Users try to access BW Reports from portal , screen always shows in Loading status as shown below,
2. Iview/Page Wizard loading issue :
3. UWL also always in loading status.
Root Cause of the issue :
During customization of com.sap.portal.layouts.framework.par , NWDS 7.0 used which deployed 7.0 version of com.sap.portal.epcf.loader.par file in deployment folder .Because of this two different versions 7.0 and 7.01 of com.sap.portal.epcf.loader.par exists which caused this conflict.
Delete the Old version com.sap.portal.epcf.loader.par file from j2ee/cluster/server0/apps/sap.com/irj/servlet_jsp/irj/root/WEB-INF/deployment/temp from OS level and deploy original file from other server. Restart the server after uploading original par file.
