• To verify against LDAP we needed a separate user other than the user trying to log into the system.
  • Also to make it easier on all parties involved instead of using new Attributes in LDAP, I had a group created that I could match up against a role of the same name in Ensemble.

So if I have an additional user I need to use to verify as the LDAP search user, how would I store the user name and password in this scenario?

So I am trying to take a list of....

managedObjects                       : {CN=Access.Ensemble.Developer.User,OU=Access Groups,DC=OSUMC,DC=EDU, CN=[CPD Admin],OU=Distribution Lists,DC=OSUMC,DC=EDU, CN=[MUSE_Access],OU=Distribution Lists,DC=OSUMC,DC=EDU, CN=[IT eMaterials],OU=Distribution Lists,DC=OSUMC,DC=EDU...}

How can I put this into a list and properly filter out the values I need. For Example Access.Ensemble.Developer.User is my end target that corresponds to a role of that same name.

I am struggling with how to appropriately pull this information out so I can do the IF statements below.

The application is sending us the following back... Of course it does not match up to any structure but like you said they probably have omitted the backslash from the ACK causing the error.

MSH|^~\&|GCRC|RDM|INTENG||20180207084732||SIU^S12|70577207|P|2.3|
MSA|AA|Successful|

I went ahead and made copies of 4 different EnsLib.HL7 classes, and modified the Parser to not throw the warning message. So for it is working like it should.

This was a custom interface written some time ago, and only maintained by hiring someone outside to update the contents of the software.

We are getting the following warning message "Discarding received non-HL7 data(1) 'r'" . We have tried different framing values to no avail, and it still wants to log this warning. We were just looking for a way to shut this warning off for just this one Operation.

I have found that the text of "Discarding Received non HL7 data" lives in the EnsLib.HL7.Parser.cls. Has anyone tired to copy and make their own HL7.Parser that would not throw this warning message? It seems pretty simple but I am having issues trying to call my updated Parser.cls. All I want to do it comment this error out so it is not thrown and taking up database space.

 

Thanks

When calling a SQL call, I normally return the value in a Snapshot. 

You can do this 1 of two ways...

1. Set two variables....One for the Outbound HL7 Message, and one for the structure of your snapshot. Set your source equal to your snapshot variable and your target being the Outbound HL7 context variable. Use a Data transformation to take the information from the Snapshot and insert it into the HL7.

2. Create a variable for your ID variable, and loop through the Snapshot to set that ID variable. Then create a dummy data transformation that you can use to set your HL7 field to your context.ID variable.

I have plenty of examples of doing this in either way. There might be others that have a better solution, its just what I have used in the past.

No luck but thanks.

I took the query from $$$LOGINFO(select)  and executed it fine in SQL Server. It showed Ensemble should of returned 185 rows.

For every database pull Ensemble stores either that whole message or a key value so it knows that record has already been read.  I can't figure out how to get around that when I do a ExecuteQuery() call inside my Operation.
