Problem with ALV display of data

[former_member1317944]

Hi Experts

I have 2 views, view1 and view2. In View2 I have an ALV grid but in the wddoinit I hide certain columns using if_salv_wd_column_settings~delete_column. Lets say the context node has attribute a,b,c,d and I hide columns a and b. When I navigate from view1 to view2 the alv displays columns c & d perfectly with their data. But if I navigate from view2 to view1 and then back to view2, the data is out of sync with the columns. In other words column c and d has context a and b data in it?

I have changed the lifetime to "when visible" for view2 so that the wddoinit method is called each time but the result is the same. Please help

I've fixed it.

When I call the method set_cell_editor the columns were out of sync second time around. Thanks for your responses.

Hi,

The data that you see in your ALV is the data which you bind to your context attributes. Please debug and check at the place where you are binding the data if the data is getting binded to the correct attributes.

hi,

Check whether your Wddoinit () of View2 is called second time or not ?

If yes, make the columns invisible in Wddoinit().

If your wddoinit() of view 2 is not called , then you can hide the columns while firing the view 2.

Hi Saurav

Wddoinit is called both times. I dont see why my code will work the first time and not the second time.

Hi,

For a given session, WDDOINIT gets called only once. Hence write the code in the INbound plug handler of 2nd view.

Hi,

Please write the code of WDDOINIT in the handler(iplug) of 2nd view.

Hi Lekha

The code is modularised but wddoinit calls method set_fields where I setup read only fields

and then method configure alv where I change column descriptions and hide columns. See below:
