There are 3 possible symptoms to this issue:
1. MDM Portal iViews image fields are not displaying image. Instead of the linked image, a red “X” is displayed. In addition, Portal DefaultTrace file will contain the following entry:
Access denied (Object:com.sap.portal.system/security/com.sap.pct.mdm.appl.masteriviews/low_safety).
2. When trying to open any Pop-up window in the MDM Item Details iView you get a “Portal Running environment error”. In the Portal DefaultTrace file you see the following entry:
com.sapportals.portal.prt.runtime.PortalRuntimeException: Access is
denied: com.sap.pct.mdm.appl.masteriviews.QualifierRowPopupViewer -
user:
com.sapportals.portal.prt.deployment.DeploymentManager.checkPermissions
Caused by: com.sapportals.portal.pcd.gl.PermissionControlException:
Access denied (Object(s): com.sap.portal.system/security/com.sap.pct.mdm.appl.masteriviews/low_safety).
3. When attempting to open a Pop-up, the Popup window opens up with a generic exception error message: “Portal runtime error. An exception occurred while processing your request……Refer to the log file for details about this exception”. The Default Trace log has no additional information”.
Other terms

MDM, iView, Portal, Item Details, Image, Pop-Up, low_safety
Reason and Prerequisites

The key words to note from the log are: Permissions, low_safety.
The above would suggest that the user that has opened the pop-up window does not have sufficient permissions, and hence the image/popup will not display the data.
Solution

Change the portal permission to address the above 2 issues:
Logon to portal with Super Administrator role.
Go to – System administration ==> Permissions ==> com.sap.pct.mdm.app.masteriviews ==> low_safety.
Select this node and then add the portal group “everyone”, tick the End User check-box. The attached screen capture ‘Low_Safety.png’ sample shows what the permission looks like after you apply this configuration.
