Dynamic Possible Values for Parameter Fields

[Former Member]

Hi,

Can anyone throw some idea on how to implement Dynamic possible value list for parameter field.

I have three parameter fields with F4 option. First Company Code; if the user selects a company code from the list only valid personnel areas of that company code should be available for second field (Personnel area).

And the third field Personnel Sub Area should display only valid entries for selected Personnel Area in the second field.

Thank you,

Hey,

When the user takes the F4 help on the 2nd field you need to read the value entered in the company code field using the function DYNP_VALUES_READ and show the entries relating to the entered company code.

Similar logic has to be implemented for the F4 help on the 3rd field.

DYNP_VALUES_READ function is the key...

Ram,

See the below example. You could use same technique, or a search helf if exists , or the F4* function modules.

Cheers,

Thomas.

Hello,

U can do it through the FM F4IF_INT_TABLE_VALUE_REQUEST.

Once the User Gave the companz code in the first field,

Then select the personal area of that company code and pass it to the FM F4IF_INT_TABLE_VALUE_REQUEST.

DO the same for the third field also.

Before selecting check the BUKRS field is initial or not.

Reward if useeful.
