Thanks for reporting it. I'll take a look as soon as I can, which may take
a few days as this is a side project for me.

Hi,
I am reading CWR file through this Data-api library. I am getting the
following exception.
**File "C:\Python34\lib\site-packages\pyparsing.py", line 2794, in parseImpl
raise ParseException(instring, loc, self.errmsg, self)
pyparsing.ParseException: Expected sd_type (at char 114), (line:2, col:27)**
Have tested on Python 2.7, Python 3.4 and Python 3.6. Getting same
exception. Any help would be appreciated.
Here's the full stack trace of the program.

Sorry I couldn't take a look sooner.
For what I can gather a line in the file is missing the SD Type, composed of two alphanumeric letters at the end of a group header (a GRH row).
Could you please verify that?
The parser is very strict, so something like that can break the parsing.

I have provided different CWR file including the one you have included in tests/example folder as input. Then also I am getting the same error.
There is a note in CWR functional document that states
"Submission / Distribution Type is used only in the case of audio-visual transactions. This field
will be ignored for CWR transactions".
SD_Type is a non mandatory field according to CWR functional document.

I've set the SD type as optional, also uploaded a new version to Pypi with the latest changes. Could you try it now?
Sorry it is taking so long, but I do this on my spare time.

After taking a better look, the problem won't be solved in the short term. There are some problems with the grammar used by the parser and acknowledgement files, which are related to this issue.
