Hi
My es return looks like this..
{
"took": 31,
"errors": false,
"items": [{
"index": {
"_index": "orders",
"_type": "order_item_manuscript",
"_id": "161001030000000000000000000002",
"_version": 4,
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"status": 200
}
}
}]
}

My ABAP structures look like this
DATA: BEGIN OF index ,
_index TYPE STRING,
_type TYPE STRING,
_id TYPE STRING,
_version type i,
begin of _shards,
total type i,
successful type i,
failed type i,
end of _shards,
status TYPE i,
END OF INDEX.

data: begin of es_return,
took type i,
errors type string,
begin of items,
index LIKE TABLE OF index,
end of items,
end of es_return.

I only capture took and errors when converting json to es_return but not items...any ideas what could be wrong?
