Don't you think the problem might be StoreFieldStreamBase64 using Base64Encode from %SYSTEM.Encryption with default flags value at 0 ?

I'll try encoding the stream myself and using StoreFieldStreamRaw instead of  StoreFieldStreamBase64

If my solution doesn't work i'll try yours :)

Thanks

Second option : An OBX:5 with the value ABCDEFGHIJKL (get rid of all crlf)

[Updated last comment with code]

I need to add a file inside the obx:5(1) segment as a base64 encoded stream.

I'm using the StoreFieldStreamBase64 method from EnsLib.HL7.Segment.

This method add extra escaped CRLF inside my OBX segment and i don't know why.

When i write the hl7 message on disk with the new OBX segment, i can't parse it anymore with an EnsLib.HL7.Service.FileService, the extra crlf character is the problem.

Maybe i'm doing something wrong in my way to process the file.

Hello, thanks for your answer.

Here is how i store the base64 stream inside my obx segment : 

s stream=##class(%FileBinaryStream).%New()
s stream.Filename = filename
s propertyPath = "PIDgrpgrp(1).ORCgrp(1).OBXgrp(1).OBX:5(1)"
s seg=target.GetMutableSegmentAt($P(propertyPath,":",1),.tSC)
s tSC = seg.StoreFieldStreamBase64(.stream,$P(propertyPath,":",2),,0)

Here is the result :

JVBERi0xLjQKJeLjz9MKNCAwIG9iago8PC9UeXBlL1hPYmplY3QvQ29sb3JTcGFjZS9EZXZpY2VH\r\ncmF5L1N1YnR5cGUvSW1hZ2UvQml0c1BlckNvbXBvbmVudCA4L1dpZHRoIDEzOS9MZW5ndGggMTM3\r\nMi9IZWlnaHQgN

EX : OBX|1|RP|5142648||ABCD[CR][LF]EFGH[CR][LF]IJKL....

I don't know why there is multiple extra \r\n in the obx segment.

And when i use a EnsLib.HL7.Service.FileService, my HL7 Object OBX:5(1) hold only ABCD information.
