Answer / srikanth
Session Device error occurs when try to display empty subfile. To avoid this, on indicator associated with SFLINZ keyword. Another case session device error occurs when EXFMT subfile control record with out subfile control indicator is on.

Answer / krisalli
some more cases...
- Incorrect record number in subfile SFLRCDNBR or SFLSIZ field.
- In program code, at display (EXFMT) subfile code, check the value of RRN. If is zero and you are making on the SFLDSP indicator *ON or it is un-conditional and doing display subfile. Then it will give you the same error.
- Trying to show empty subfile.
- Field and position in Display file DDS is not correct.
- The keywords are not properly organized in Display file DDS.
- Trying to write more than 9999 record on the Display file for Load All subfile

along with the WORKSTN files.
