Specifying picture informant in order to read specific datetme string - datetime

Question

I would like to read the "19-APR-21 18.17.06.301100" the string into a DATETIME and display accordingly. In order to achieve that I'm intending to define a display format and an informat as provided in the example below.
Example
* Define formats to read and display data;
* Input format;
PROC FORMAT LIB=work;
PICTURE indte other = '%d-%B-%y %H.%M.%S.%s'
(DATATYPE=DATETIME);
RUN;
* Nice display format;
PROC FORMAT LIB=work;
PICTURE outdte other = '%d %B %y %H:%M'
(DATATYPE=DATETIME);
RUN;
* Test with sample data;
DATA text;
strdate = "19-APR-21 18.17.06.301100";
RUN;
* Apply informat and display format;
DATA pretty(RENAME=(strdate=nicedte));
SET work.text;
ATTRIB strdate INFORMAT=indte.;
FORMAT strdate outdte.;
RUN;
Problems/questions
The DATA pretty procedure is not able to load the define formats and returns the following error:
NOTE 485-185: Informat $INDTE was not found or could not be loaded.
NOTE 484-185: Format $OUTDTE was not found or could not be loaded.
Is this an efficient way of doing this for the data that in the proper process is sourced via: infile <file ref created by filename> delimiter=',' stopover firstobs=2 dsd lrecl=32767;?

Answer 1

PICTURE is used to create a FORMAT, not an INFORMAT.
The ANYDTDTM informat should handle strings in that style. But it will ignore the fractions of a second.
DATA text;
strdate = "19-APR-21 18.17.06.301100";
datetime = input(strdate,anydtdtm.);
format datetime datetime26.6 ;
put (_all_) (=/);
RUN;
Results:
strdate=19-APR-21 18.17.06.301100
datetime=19APR2021:18:17:06.000000
If you need the fractions of a second then parse the string and read it separately.
datetime = dhms(input(strdate,date9.)
,input(scan(strdate,2,' .'),2.)
,input(scan(strdate,3,' .'),2.)
,input(scan(strdate,4,' .'),2.)
+input(scan(strdate,5,' .'),6.6)
);
