Hello,
i've found the place in the coding.
Class: CL_SALV_GUI_FIELD_CATALOG_IDA
Method: GET_ALLOWED_SERVICES
if ls_display_info-is_text_search_allowed eq abap_true
and l_inttype NA 'IPbsaef'
AND l_convexit IS INITIAL. "OR l_inttype EQ 'N' ). "Not Numeric and no ConvExit U4YK011340
is_text_search_allowed = abap_true.
endif.
The Conversion Routine has to be initial. Is there any special reason?
Please change the SAP Standard! :-D
Best regards
Frank
