Here is some documentation from SAP on Dynamic Programming in WDA. If this doesn't answer your question, could you please provide more detail on what you'd like to do with dynamic programming?
Amy i have two fileds named COST CENTER & PROFIT CENTER with 9 rows in the table & i need to populate that table at runtime by creating dynamic structure related to it.....
If I understand correctly, you have a table UI element with two fields, cost_center and profit_center, and you want to populate the table.
Have you defined a 0..n or 1..n context node with attributes cost_center and profit_center and bound your table to the context node? If you have done this, you don't need dynamic programming; you can populate the table by writing a supply function for the context node. The supply function will be called automatically by the WDA runtime when the node is initialized and your table will be populated.
For example:
method supply_mynode .
data ls_mynode type wd_this->element_mynode.
data lt_mynode type wd_this->elements_mynode.
do 9 times.
ls_mynode-cost_center = the_value.
ls_mynode-profit_center = the_value.
append ls_mynode to lt_mynode.
enddo.
node->bind_table(
new_items = lt_mynode
set_initial_elements = abap_true ).
endmethod.
