F4IF_INT_TABLE_VALUE_REQUEST + ALV Grid

Former Member — Wed, 15 Oct 2008 08:31:43 GMT

Hi All,

I have a ALV grid with 2 fields.

I implemented F4 for field1 using the FM below.

I get a list of values as expected when i use 'F4', however the selected value is not written back to the ALV grid field!

What am i missing here?

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = lv_retfield_name

value_org = 'S'

tables

value_tab = lt_f4tabletmodel

field_tab = lt_return_tab

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

Note: the internal table lt_return_tab[], contains the value i selected, but i expect this to be written to the ALV grid field for which F4 was performed.

Thanks in advance and Regards

Dev

are you using Object Oriented ALV. if so check the example BCALV_EDIT_08 . after you select the value you have to update the value and use refresh_table_display method.

hi ,

in the function module u have to pass the parameter dynpro field.

ex: dynprofield = 'P_ID_LOW' // that is ur parameter or select option low or high.

Hi,

I'll try to be more precise.

I have a ALV grid with 2 columns.

I add a row to a grid.

For the first field in the newly added row, i perform a F4 using the FM mentioned.

I get the values also.So far so good.

However on selecting a value from the popup, the value doesnt' get transferred to the grid

The refresh_table_display method instead also removes the new line i added to the grid!!!

More pointers?

Thanks in advance.

<lf_f4_data> is your internal table ..? where are you modifying the record of the internal table..? and after modification call the refresh_table_display method.
