get record not satisfying join condition

Hi Team,

I am facing issue in fetching the record which do not satisfy the join condition. Below are details-

table1

MATERIAL  SOURCE_PLANT

M1                SYW1             

M2                 SWW1

M4               AABB

M5              AEW1

M6                AYW1

M7               AABB

table 2

MATERIAL RECEIVING_PLANT  SOURCE_PLANT PROC_TYPE

M1              AEW1                              SYW1               SY

M2              AYW1                              SWW1              SW

M3               AZW1                              DWW1               DW

Now I need to check the material and source plant combination records from the table2 in table1

Ex- M1 and SYW1 exist in table1 so I need to skip this record

similarly M2 and SWW1 exist in table so I need to skip this record

M3 and AZW1 DOES NOT exist in table1 hence I need to LIST this record in my output..

How to achieve this in HANA model-

I have written a script for this as below but is not working-

SELECT t1."MATNR", t1."Source_plant"FROM"_SYS_BIC"."pk-sample.safetystock/ZCV_MARC" t1

WHERENOTEXISTS

(selectt2.MATNR, t2.source_plant from"_SYS_BIC"."pk-sample.safetystock/ZAN_MARC" t2 where

t1.MATNR = t2.MATNR

AND t1.WERKS = t2.source_plant)

groupby"MATNR" , "SOBSL";
