Simple Value Help on DropDown via KeyValue leads to short dump after select

28 Views

Hi,

I did not succeed in preparing a value help via a key-value table.

Although the DropDown Box shows the entries of the table correctly when selecting (note: onSelect action must be existent) there occurs an error that states that the selected key does not exist. Nevertheless the key does exist, mapped by the set_attribute_value_set method..

Can anyone of you make things more clear for me?

The coding is more or less a 1:1 copy from code that can be found in the sappress book as well as on the internet - only slightly adapted.

I would expect a use-and-forget approach: use the set_attribute_value_set method once and no problems from then. Is it perhaps a bug? I was not able to find related SAP Notes for this.

Find code and error message below.

Best regards,

Marc
