When dealing with JOLT Spec, we can predefine some constant which starts with <STRONG>"#" for the unexist value scope&nbsp;</STRONG>"#&lt;constant&gt;", in that way we can then handle the rest match-and-shift work .</P><P>&nbsp;</P><LI-CODE lang="markup">[ { "operation" : "shift", "spec" : { "logTypeCode" : { "FIN" : { "#END_OF_TESTING" : { "$":"body.&amp;3", "#END_OF_TESTING":"customValue.logTypeCode" } } }, "*" : "body.&amp;", "#${date}" : "header.date", "#${env}" : { "$" : "customValue.ENV" } } } ] ============== OR ============== [ { "operation" : "shift", "spec" : { "logTypeCode" : { "FIN" : { "#END_OF_TESTING" : { "$":"body.logTypeCode", "#END_OF_TESTING":"customValue.logTypeCode" } } }, "*" : "body.&amp;", "#${date}" : "header.date", "#${env}" : { "$" : "customValue.ENV" } } } ]</LI-CODE><P>&nbsp;</P><P>&nbsp;&nbsp;<BR /><BR />Hope this helps.<BR />Thanks</P> Fri, 14 Jan 2022 22:40:46 GMT OliverGong 2022-01-14T22:40:46Z
