Thanks Shirish, for finding the root cause of this issue , I and Ram were able to replicate the same issue after accessing the SAS code in sas studio portal manually from a purpose with blank space or a control character in their name, then we could not be able to open any SAS file from any purpose using the pencil icon in sigma application.
Code Fix - SIGMA dev team should handle character conversion when writing directly in the .key file or restrict NBSP character in purpose name when user create new purpose in sigma SCE.
Following users have created purpose with blank space ( “M-BM-“ character ) on the purpose name. The M-BM- characters are an ASCII representation of byte sequence 0xc2 0xa0 , which is the UTF8 encoding of unicode character A0 - a non-breaking space character.
