Doubts in F4 help

Hi,

You cannot make that as non-editable.But here is the way that you can restrict other values in module pool.If you pressed enter after executing this code,then if that value entered is not in f4 help,it will automatically be removed.

PROCESS AFTER INPUT.

FIELD s_begru MODULE abc ON INPUT.

Process on value-request.

field s_begru module f4_help.

REPORT ZZZ_JAYTEST1 .

tables kna1.

data:

begin of t_values occurs 2,

value like kna1-begru,

end of t_values,

t_return like ddshretval occurs 0 with header line.

data s_begru like kna1-begru.

call screen 9000.

module f4_help input.

refresh t_values.

t_values = 'PAR*'.

append t_values.

t_values = 'UGG'.

append t_values.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'BEGRU'

value_org = 'S'

tables

value_tab = t_values

return_tab = t_return

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

if sy-subrc = 0.

read table t_return index 1.

s_begru = t_return-fieldval.

endif.

endmodule. " f4_help INPUT

module abc input.

read table t_values with key value = s_begru.

if sy-subrc ne 0.

clear s_begru.

endif.

endmodule. " abc INPUT
