Hi,

You can make use of the field <tablecontrol>-currentline but it will create a problem when you press page down .So you need to use a small logic.

Process on value request.

index = tc1-topline - tc1-currentline + 1.

read internal table at index.

select from table for value selected and populate in an internal table..

then there is a function module "F4IF_INT_TABLE_VALUE_REQUEST" where we can pass the internal table and return values will be populated in the table control.

hi

good

try this

F4IF_INT_TABLE_VALUE_REQUEST F4 help that returns the values selected in an internal table. Very handy when programming your very own F4 help for a field.

Example:

data:

begin of t_values occurs 2,

value like kna1-begru,

end of t_values,

t_return like ddshretval occurs 0 with header line.

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.

o_begru-low = t_return-fieldval.

if o_begru-low = 'PAR*'.

o_begru-option = 'CP'.

else.

o_begru-option = 'EQ'.

endif.

o_begru-sign = 'I'.

append o_begru to s_begru.

else.

o_begru = i_begru.

endif.

thanks
