Sap connector pb loading data

[#1]

Hi everyone,

i work with sap connector 5.2 and sap 4.6. Connector installation is ok.

in my qvw i test a this request (use connector). I obtain several row

SQL Select VKORG VTWEG SPART VBELNKUNNR WAERK ERDAT ERNAM KTEXT AUART AUGRU AUDAT NETWR BUKRS_VF VKBUR VKGRPVDATU

FROM VBAK ;

But if i use this request, i have no error just qlikview say me 0 row:

SQL Select *

FROM VBAK ;

My question is

does it exist restriction field to load data in SAP or qlikview connector has a restriction of field number?
