In the past we had issues with editn_xtn in 6.1 and 6.5, when not dropped posting another TN document will create issues in TN Console saying document is Unknown.Is it going to be deprecated in the future releases?
editn_txn doc (holds the transaction set data) is still exist in the latest releases…its available when you have the X12 Transaction Set as the document type selected in the TN rule and the processing service will have this reserved var in the pipeline apart from edidata.
