issue in view creation on HANA DB

Dear Team,

I have replicated two tables from ECC to HANA using SLT.

I am creating a DB view on HANA DB using below code. But unfortunately it could not able to create it.

Syntax:

create view covj as ( select * from COBK,COEJ where(COBK.MANDT = COEJ.MANDT ) AND  ( COBK.KOKRS = COEJ.KOKRS ) AND

        ( COBK.BELNR = COEJ.BENR ));

Issue:

Could not execute 'create view covj as ( select * from COBK,COEJ where ( ( COBK.KOKRS = COEJ.KOKRS ) AND ( COBK.BELNR ...' in 267 ms 307 µs .

SAP DBTech JDBC: [268]: column ambiguously defined: MANDT: line 1 col 8 (at pos 7)

Regards,

jo
