Question

I have a selection screen 1. PO Number(p_ebeln)(parameter) 2. PO Date(s_budat)(Select-options) 3.PO Item(s_ebelp)(Select-options).What I want is when I am providing a PO(eg.6000001) and then click on the F4 for PO date it will show me ONLY the BUDAT for the corresponding PO I have provided in the PO parameter(eg.6000001) and when I press F4 in the PO Item it will show me those PO ITEM which ONLY exist for the corresponding PO I have provided in the PO parameter(eg.6000001).

Hi,
If my understand your question correctly, You want to use the PO entered by user to select the date and item numbers in subsequent select-options.
Here is what you can do to achieve this:
1. You have to make use of AT SELECTION-SCREEN ON VALUE REQUEST for date and item numbers.
2. Read the PO number provided by user by using FM DYNP_VALUES_READ
3. From the PO number select date and item numbers from EKKO&EKPO.
4.Use the FM F4IF_INT_TABLE_VALUE_REQUEST to set the values coming when user press F4
You can refer following article also for code samples:

let me know if this helps.
Thanks,
