Deletion of Transaction History
Over time, the amount of transaction history maintained by the system can get very large and cumbersome. SinceWindchill ESI needs this transaction history to determine which objects need to be published in future publishing activities, the actual data cannot be deleted from the system. Instead, the history can be marked as deleted so that it can be hidden from the end-user and not shown in the reports.
Windchill Integration for MES uses ISA-95 B2MML for data exchange. This standard defines its own Transaction model. This integration maps one ESI Transaction to many B2MML transactions; the message for one ESI transaction is transformed into many B2MML transactions and then all these messages are zipped and sent over a delivery channel.
B2MML supports the following transaction model:
Sr. No.
Model
Request Verb
Response Verb
Notes
1
Pull
GET
SHOW
Request for data.
2
Push
PROCESS
ACKNOWLEDGE
Typically an add request.
The definition of word “process” as meaning “deal with” or “handle”. A PROCESS verb is often the equivalent of a command to add the data, but usually the receiving entity performs further actions as a result of receiving the data.
CHANGE
RESPOND
CANCEL
n/a
Typically a delete request. May optionally request a ConfirmBOD response message.
* 
The request to cancel indicates that the sender no longer needs the data. Because the CANCEL is not sent by the owner of the data, the data are not necessarily deleted.”
3
Publish
SYNC‑ADD
n/a
May optionally request a ConfirmBOD response message.
SYNC‑CHANGE
n/a
May optionally request a ConfirmBOD response message.
SYNC‑DELETE
n/a
May optionally request a ConfirmBOD response message.
A “Publish” model is used for data exchange for a B2MML transaction.
Each B2MML message has the information about the ESITransaction and ESIRelease object for Windchill Integration for MES that can be used to correlate messages with the Windchill ESI transaction.
