Formatted Search on HANA not returning values

Experts,

I have a FMS on a Sales Order row UDF that needs to bring back a list of Vendor Ref. No (NumAtCard) if the other Row UDF have that Vandor name filled in.

Because this is on HANA, I do not have access to the system information, so I guessed as best I could.

SELECT T0."NumAtCard"

FROM OPOR T0

WHERE T0."CardName" = $[$38.U_XXX_MD_03.0]

Any help would be appreciated.
