Lately, I am facing some error “LIST_TOO_MANY_LPROS” when using SAPGUI for Java 7.20 rev 9 to access SAP ERP 6.0 EHp 5 with Basis release 702 SP 12 (KB70212). Then I search this on service.sap.com and found this useful SAP Notes 17447011.
Accessing Implementation Guide through SPRO in HTML & JAVA GUI results in Runtime error as LIST_TOO_MANY_LPROS
Reason and Prerequisites
While accessing IMG through SPRO in HTML & JAVA GUI, it results into run time error as LIST_TOO_MANY_LPROS.
This is because of some method calls are failing to be implimented in JAVA and HTML GUI.
Manual Steps to be followed:
1. Enter T-Code ‘SPRO’.
2. Click on ‘Settings’..’User-Specific Settings’..’General’
3. Uncheck all the check boxes.
4. Restart the t-code ‘SPRO’.
By this, some of the Control features cannot be accessed,
but the IMG navigation is possible.
Now, I am able to access SPRO smoothly again.
