Hi,
In my ALV list for the same column I need Button or Value for the different rows (CELL) depending upon my condition.
as well as I have to make read only of 3 rd column CELL based on my first column dropdown value CELL for this Row Only.
Depends upon the value in column 1 / row 2 I have to read only the CELL of column 5 / row 2 ie for the same row.
Depends upon the value in Column 1/ row 3 I have to EDITABLE or Button the CELL of column 5 / row 3 ie for the same row
How to do the logic for this.
I tried and got it for the entire column only.
But my requirement is for the sepecific cell in the column.
Kindly help to proceed further.
Thanks in advance.

Here is how you can make a particular cell in the row read-only based on certain conditions.
In my example I am displaying the flight details in an ALV. Here I am checking the airline id and if it is "AA' I am making the cell in the column airline id as readonly. In my example I am putting a check and readonly on the same column. However you can do this for different columns as well.
In order to achieve this you need to add a new context attribute 'READONLY' of type abap_bool to the context node which is bound to data node of ALV.
The method where I populate the node has the following code to populate the data.
data: lr_input_node type ref to if_wd_context_node,
lr_flight_node type ref to if_wd_context_node,
lv_cityfrom type s_from_cit,
lv_cityto type s_to_city,
ls_from type bapisfldst,
ls_to type bapisfldst,
lt_flights type table of bapisfldat,
ls_flights type bapisfldat.
data: lt_final type if_mainview=>elements_node_flighttab,
ls_final type if_mainview=>element_node_flighttab.
* Instantiate the variable lr_input_note to the node NODE_FLIGHT
lr_input_node = wd_context->get_child_node( name = 'NODE_FLIGHT' ).
* Instantiate the variable lr_flight_note to the node NODE_FLIGHTTAB
lr_flight_node = wd_context->get_child_node( name = 'NODE_FLIGHTTAB' )
.
* Get the attributes CityFrom und CityTo
lr_input_node->get_attribute( exporting name = 'CITYFROM'
importing value = lv_cityfrom ).
lr_input_node->get_attribute( exporting name = 'CITYTO'
importing value = lv_cityto ).
* Fill the stuctures ls_from and ls_to
ls_from-city = lv_cityfrom.
ls_to-city = lv_cityto.
* Call the function BAPI_FLIGHT_GETLIST
call function 'BAPI_FLIGHT_GETLIST'
exporting
destination_from = ls_from
destination_to = ls_to
tables
flight_list = lt_flights.
Now I am going to check if the airline id is 'AA' and based on that I will fill the readonly context attribute.
loop at lt_flights into ls_flights.
MOVE-CORRESPONDING ls_flights to ls_final.
if ls_flights-airlineid = 'AA'.
ls_final-readonly = abap_true.
else.
ls_final-readonly = abap_false.
endif.
append ls_final to lt_final.
endloop.
Finally bind the data to the context node.
* Bind the data to the node NODE_FLIGHTTAB
lr_flight_node->bind_elements( lt_final ).
Now you need to do the ALV configuration settings.
* create an instance of ALV component
DATA:
lr_salv_wd_table_usage TYPE REF TO if_wd_component_usage.
lr_salv_wd_table_usage = wd_this->wd_cpuse_alv( ).
IF lr_salv_wd_table_usage->has_active_component( ) IS INITIAL.
lr_salv_wd_table_usage->create_component( ).
ENDIF.
* get ALV component
DATA:
lr_salv_wd_table TYPE REF TO iwci_salv_wd_table.
lr_salv_wd_table = wd_this->wd_cpifc_alv( ).
wd_this->alv_config_table = lr_salv_wd_table->get_model( ).
CALL METHOD wd_this->alv_config_table->if_salv_wd_table_settings~set_read_only
EXPORTING
VALUE = ABAP_FALSE
.
* set visible row count
DATA:
lr_table_settings TYPE REF TO if_salv_wd_table_settings.
lr_table_settings ?= wd_this->alv_config_table.
lr_table_settings->set_visible_row_count( '10' ).
DATA:
lr_column_settings TYPE REF TO if_salv_wd_column_settings,
lr_column TYPE REF TO cl_salv_wd_column.
lr_column_settings ?= wd_this->alv_config_table.
DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
lr_column = lr_column_settings->get_column( 'AIRLINEID' ).
CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'AIRLINEID'.
lr_column->set_cell_editor( lr_input_field ).
lr_input_field->set_read_only_fieldname( value = 'READONLY' ).
CALL METHOD lr_column_settings->delete_column
EXPORTING
id = 'READONLY'

You can use cell variants for this purpose.
You need to add a context attribute 'VARIANT' of type string to the context node which is bound to data node of ALV.
Here I am trying to display to display a button in the column airline if the airline id is 'AA" otherwise a input field.
Change the method where you fetch the data
loop at lt_flights into ls_flights.
move-corresponding ls_flights to ls_final.
if ls_flights-airlineid = 'AA'.
ls_final-readonly = abap_true.
ls_final-variant = 'BT'.
else.
ls_final-readonly = abap_false.
ls_final-variant = 'IN'.
endif.
append ls_final to lt_final.
endloop.
Add the following code to the method where you are doing ALV config settings.
* setting cell variants
data: lr_column_airline type ref to cl_salv_wd_column.
data: lr_cv type ref to cl_salv_wd_cv_standard.
data: lr_button type ref to cl_salv_wd_uie_button.
lr_column_airline = lr_column_settings->get_column( 'AIRLINE' ).
* Add cell variant input field
create object lr_cv.
call method lr_cv->set_key
exporting
value = 'IN'.
create object lr_input_field exporting value_fieldname = 'AIRLINE'.
call method lr_cv->set_editor
exporting
value = lr_input_field.
call method lr_column_airline->add_cell_variant
exporting
r_cell_variant = lr_cv.
* Add cell variant button
create object lr_cv.
call method lr_cv->set_key
exporting
value = 'BT'.
create object lr_button.
call method lr_button->set_text
exporting
value = 'Button'
.
call method lr_cv->set_editor
exporting
value = lr_button.
call method lr_column_airline->add_cell_variant
exporting
r_cell_variant = lr_cv.
call method lr_column_airline->set_sel_cell_variant_fieldname
exporting
value = 'VARIANT'.
