Summary :
The issue described involves the OPEN DATASET command with the FILTER addition in SAP, which returns SY-SUBRC = 0 even if the file does not exist or cannot be written to. When using CLOSE DATASET on such files, SY-SUBRC may reflect values like -1, 256, or others not ordinarily set by the filter. When OPEN DATASET ... FILTER is used, a pipe and an additional process execute the filter command, but this subprocess may terminate early, leading to SY-SUBRC inconsistencies. Solutions include verification of SY-SUBRC upon CLOSE DATASET and adhering to guidelines for exit codes and EOF handling for reliable command execution.
