ALV tree problem in refreshing ( get a dump when refresh) ?

[Former Member]

hi gurus,

In my program I use ALV tree to display the data like :

Root

Child 1

Child 1 1

Chiild 1 2

Child 2

Child 2 1

Child 2 2

....................................

When I refresh data ( internal table) , If there's no new node ( for example : add child 3) , It 's OK but if there's new record in the internal table ,,,when refresh there will be a dump... in my opinion, The new node must have a new node key? But I do not find a solution...

Could you please help me?

Thanks in advance.

Hi TinhLangTham ,

you cumulute call of your dynpro.

DYNP1 --> Action --> Call again DYNP1 --> action --> Call again DYNP1

and when you leave or anything else, you will need to close 3 times DYNP1.

have a look where you call and how, the screen.

or you can choose the other way

refer to to CL_GUI_ALV_TREE and not CL_GUI_ALV_GRID.

In CL_GUI_ALV_TREE REFRESH_TABLE_DISPLAY is a private method.

try using method FRONTEND_UPDATE of CL_GUI_ALV_TREE .

Hi,

If you are using CL_GUI_ALV_TREE.

CALL METHOD TREE1->EXPAND_NODE

EXPORTING

I_NODE_KEY = ALL_KEY

I_EXPAND_SUBTREE = 'X'.

'ALL_KEY' is the root node of the tree.therfore will refresh the whole tree, with subtree thus it may solve your problem.

Try the code .

thanks and regards
