update on HANA column base table

Hello,

We are trying to update a column base table which contains 600M records with the following statement:

UPDATE

      "SLT_RDL"."SBA_SF_DATA" SET  

          "/BIC/CINTRCLSS" = '3' WHERE   

  "/BA1/IGL_ACCOUNT" in (        '0000013500')

This statement should update 5M records but ends with out of memory...

Can someone please suggest how can we update the table?

Thanks, Amir
