Invalid physical name

[Babloo]

I'm using file writer transformation in my DI job to create the .txt file. After the successful execution of the job, when I tried to open .txt file, I'm getting an error like "Invalid Physical file". Code generated by file writer transformation as follows.

data _null_; 
   set &SYSLAST; 
      attrib TBKPAR length = $2; 
      attrib CRI length = $12; 
      attrib P2KBRN length = $2; 
      attrib CRIHIS length = $12; 
      attrib P2KBRH length = $2; 
      attrib SD length = $9; 
      attrib S2KBRN length = $2; 
      attrib XXAROL length = $8; 
      attrib PSI length = $9; 
      attrib HDK length = $3; 
      file "!FSB/common/life_details_crdb_50_tmp_timestamp.txt" lrecl=1226;
      
         put 
             @ 1 TBKPAR  
             @ 3 CRI  
             @ 15 P2KBRN  
             @ 17 CRIHIS  
             @ 29 P2KBRH  
             @ 31 SD  
             @ 40 S2KBRN  
             @ 42 XXAROL  
             @ 50 PSI  
             @ 59 HDK  
         ;
   
run;

Appreciate if someone of you help me understand the likely cause for this issue.

How do you try to open it?
Almost any text file generated can be opened using standard text editing tools.
