Issue with the ABAP program to find BI lookups and code Patterns

Question

Hello dears,
I'm trying to use the ABAP program LOOKUP_FINDER:
http://wiki.sdn.sap.com/wiki/display/BI/ABAPprogramtofindBIlookupsandcodePatterns
But I have the following issue:
Runtime Errors        
RAISE_EXCEPTION
Short text
    Exception condition "NO_FIELDCATALOG_AVAILABLE" raised.
Error analysis
    A RAISE statement in the program "CL_GUI_ALV_GRID===============CP" raised the
     exception
    condition "NO_FIELDCATALOG_AVAILABLE".
    Since the exception was not intercepted by a superior
    program, processing was terminated.

   17   m_cl_variant->mt_sort = it_sort.

   19   call function 'LVC_SORT_COMPLETE'
   20        exporting
   21             it_fieldcat = m_cl_variant->mt_fieldcatalog
   22        changing
   23             ct_sort     = m_cl_variant->mt_sort.
   24
   25 endmethod.
This issue is located in the FM 'REUSE_ALV_GRID_DISPLAY' called at the end of the program.... maybe because the catalog is empty?
For your information, I  called the program 'ZLOOKUP_FINDER'.
Can you help me to fix this issue?

Vince.

Hi Vince,
If a table is empty field catalog usually return no error it just display your field catalog with headers .
I think the issue is with building of field catalog .
May be some settings are missing there .
Please check FM REUSE_ALV_FIELDCATALOG_MERGE where field catalog is getting generated.
