SAP MDG Unable to Default values (using BRF+) - Single vs Multiple rows

[alexander_scn]

Experts,

I do have requirement to default values in a List UIBB (contains 5 columns and 10 rows) after retrieving the values from backend MDG (Custom Tale) - For this I'm using different derivation functions / expression combination like DB look up and Loop, but I'm not successful.

Only the first row getting populated and rest are not.

Please share your thoughts.

Thanks Mark. Further more specific to my example - am unable to default values (using Derivation) into LIST UIBB (like a table).

There is a How-To Guide on Checks and Derivations in MDG-M. Does this help?
