Partial reload with Left join issue

[sumanta12]

Hi,

When I am doing full load for the below joining table it's working fine & creating a single table:

XXX_WRITE:
LOAD
Key,
TIMESTAMP(MAX(CreatedAt_481ddbd92ed2493bb5ce1eabab8f815b))    AS MAX_TIME
FROM [lib://VVVXXX/XXXWB.qvd](qvd)
GROUP BY Key ;

LEFT JOIN(XXX_WRITE)

LOAD
Key,
CreatedAt_481ddbd92ed2493bb5ce1eabab8f815b                 AS MAX_TIME,
"Feedback",
User
FROM [lib://VVVXXX/XXXWB.qvd](qvd);

But When I am doing Partial reload and using below script it is not creating a single table instead it is creating 2 tables with synthetic key.

XXX_WRITE:
ADD LOAD
Key,
TIMESTAMP(MAX(CreatedAt_481ddbd92ed2493bb5ce1eabab8f815b))    AS MAX_TIME
FROM [lib://VVVXXX/XXXWB.qvd](qvd)
GROUP BY Key ;

LEFT JOIN(XXX_WRITE)

ADD LOAD
Key,
CreatedAt_481ddbd92ed2493bb5ce1eabab8f815b                 AS MAX_TIME,
"Feedback",
User
FROM [lib://VVVXXX/XXXWB.qvd](qvd);

How to get a single table after join in case partial reload ?
