Detect locked source file within SAP Data Intelligence pipeline

[#1]

Scenario: We are using the List Files, Read File, and Write File operators in a SAP Data Intelligence pipeline to transfer files from a source system to an Azure Data Lake.

Problem: If a file is being written to on the source system when the "Read File" operator attempts to read the file, the pipeline dies with an error since the file is "locked" and can't be opened for reading.

Question: Is there a native way to detect when a file is locked? Or what would be a suggested method to accomplish this? The intent would be to skip attempting to read the file if it is determined to be locked and move on to the next file.

Thanks.

You can try to add a new operator (e.g. Python) to handle this error, it's mostly like you receive and check the error message by the Python operator, then if the error message is “file is locked”, you put a new file into the input port.
