F4 values in dropdown

[Former Member]

Hi Experts,

I have a search help attached to an input field. The search help returns me a list of all possibel values. Can i get these values as a drop down in a DD by Key UI without any coding ? In other words, i want the F4 values as a dropdown in a dropdown UI.

Thanks,

Pris.

Hi Pris,

When using a DropDownByKey or DropDownByIndex element, the set of possible values is available automatically only for context attributes having a data type with fixed values defined in the underlying domain. So you could create a custom domain with fixed values and a related data element, and use that data element to define your context attribute.

Hi Amy,

Thanks for your reply. But these help values are not fixed values. The search help uses other other attributes to get the f4 values, so i cannot use the fixed values.

Thanks,

Pris.

Hi Pris,

If creating a custom domain to store fixed values isn't an option, you'll need to write code to populate the dropdown's value set. Take a look at .

This is exactly what i wanted to avoid since i already have the values in my search help and didnt want to write code the populate the dropdown values in context. But i guess there is no other option.

Thanks,

Pris.

Hi Pris,

The values are available in search help for input field only at runtime.

If you need the same set of entries then you can identify the selection table of search help & populate the same data to DDBK as suggested by Amy King .

Hi

Thanks for sharing the document.  If data extraction is required for populating values to dropdown field, will it be better to map a supply function with the context (related to dropdown field) rather than writing the code in WDDOINIT method ? 

If we are using the supply function, current context node information is already available in the importing parameter "NODE".  Only activity to be done is, data extraction & mapping the data to context node with NODE->BIND_ELEMENTS method.

Hi Vinod,

You can have a supply function as well for the node, but I've found that setting the attribute value set from the supply function doesn't work.

Hi Amy,

WDDOINIT works nice for populating the values, I tried to populate the "DropDownByIndex" element using a supply function as below, which worked perfectly.

DATA : lt_input TYPE wd_this->elements_input.
   SELECT vkorg FROM tvko
     INTO TABLE lt_input.
   node->bind_elements( lt_input ).

Hi Vinod,

Yes, you're correct, DropDownByIndex takes its values from a 0..n or 1..n node, so in the case of a DropDownByIndex, you can populate the node with a supply function as usual. Above, I was referring to DropDownByKey, whose data binding model differs from DropDownByIndex in that its value set is taken from a context node's context_node_info object.

Since Pris' question was about DropDownByKey, I thought you were asking about DropDownByKey too, but you're right that the text node behind a DropDownByIndex can be populated with a supply function-- in fact using a supply function in this scenario is probably a good practice.

Hi,

My bad,  I misread it as "DropDownByIndex".  Even your document describes about "DropDownByKey"
