Struggling with f4 handling in ALV grid - Minisap 46D

[sergio_atzori]

Hi to all,

I got an abap problem developing with my Minisap 46D,

and i can't realy struggle out for a solution,

Issue concern using of self defined F4 in ALV ( created via objects),

Each program (standard program as in eg.BCALV_GRID_EDIT )

given by SAP to show use of ALV self definded F4 doesn't wark at all this option,

and when i click on the cell in order to show F4 set of values, program brake down in ABAP error,

Always the same happen with my z programs when they calls method written to manage F4,

following existing examplaes i think i put instructions in the right place and in proper way:

I mean defining implementing and registering onf4 event,

Further i see that standard programs with f4 dumping on my minisap are working proper on the normal SAP at work place,

Does this depend on some Minisap strange bugs in standard ALV class? What can i do?

I would be grateful to anyone who help me solving this SAP mistery,

So I got:

Error analysis (and syntesys of the short dump )

ABAP runtime errors CALL_METHOD_CONFLICT_TYPE

The call to method "ON_F4" is incorrect

The system tried to pass field "%_DUMMY$$" to the formal parameter " ".

"CALL_METHOD_CONFLICT_TYPE"

"BCALV_GRID_EDIT " or "BCALV_GRID_EDIT "

"HANDLE_F4"

"HANDLE_F4"

or looking at my custom program:

PS. I'm not showing here code section where I register

and set handling event but is the usual, as

indicated in standard procedure,

I would recommend above all else simply upgrading:
