How to stop inserting the rows

[Former Member]

Hi all,

I have created an application in WD4A, where i added an INSERT button which creates a new row every time it is inserted. I want to put a check on it that if the rows exceed 30, it should stop inserting further rows.

being a new programmer to Dynpro, i dont have much idea about that. Please tell me how to do that & what code do i need to put to stop inserting the next row & displaying an error or Information message on the screen.

Hi Parteek,

u can use the method get_elemet count of interface if_wd_context_node to get the no of elements. Then in modify view fet focus to the alv and make the insert button hide.

eg:

in the mofify view check if the no of elements in more than u expexted

then

l_ref_interfacecontroller = wd_this->wd_cpifc_alv_name ( ).

l_reference = l_ref_interfacecontroller->get_model(

).

Data: lr_std tYPE REF TO if_salv_wd_std_functions.

lr_std ?= l_reference.

lr_std->set_edit_insert_row_allowed( abap_false ).
