            "object": "MY_ERP_TABLE_1"

• Which syntax is supported from the parser

hdbsynonym syntax (Hana 1)	hdbview syntax (XSKSynonymParser)	Comments
"<full.path.to.package>::"	location
"target" : {"schema": "..."}	targetSchema
"target" : {"object": "..."}	targetObject
"schema"	synonymSchema

• Parser behavior (issue)

• Currently the Parser do not take into account if a given property is mandatory.

• If the property order is misplaced the parser will still parse the values.

• If more than one value of one property is provided then only the last one is taken.

• The following examples will be parsed:

{
  "kneo.test.db::Test.dvMySynonym1": {
    "target": {
      "schema": "SYS",
      "object": "DUMMY"
    },
    "schema": "TONI"
  }
}

{
  "kneo.test.db::Test.dvMySynonym1": {
    "schema": "TONI",
    "target": {
        "object": "DUMMY",
        "schema": "SYS"
    }
  }
}
