    Hi Rahul,

    The sync recipe won't work, as there is no control over the filenames produced by visual recipes (unless you do it manually, as I explained earlier). So instead of using the sync recipe, you can create a managed folder using the sftp connection and save files directly from the python recipe into the managed folder using the upload_stream() method. Please refer to the code example below:

    import dataikuimport pandas as pd, numpy as npfrom dataiku import pandasutils as pdu# Read recipe inputsdataset = dataiku.Dataset("dataset_name")df = dataset.get_dataframe()#generate your custom name with your own logicmy_custom_name = "my_custom_name1.csv"# Write recipe outputs to the sftp managed foldersftp_folder = dataiku.Folder("folder_id")sftp_folder.upload_stream(my_custom_name, df.to_csv(index=False).encode("utf-8"))

    Hope this helps.

    Best,

    Vitaliy

    Hi,

    Please provide more details so we can better understand the issue:
    1) What input data timestamp values do you have? Is it something like "2017-07-01 12:00:00.000" or something else? It would be even better if you could attach a sample file.
    2) What output do you get?
    3) What is desired output?

    Best,

    1) What input data timestamp values do you have? Is it something like "2017-07-01 12:00:00.000" or something else? It would be even better if you could attach a sample file. - Yes
    2) What output do you get? - out-s0.csv
    3) What is desired output? - file must be save like this market_name_project_name_timestamp.csv example za_offer_recommendation_2017-07-01 12:00:00.000.csv

    Files and Folders are also getting deleted in server after every run

    There is no such functionality to set the file name automatically. You can do it manually from the dataset Settings > Advanced page by Forcing it to a single output file and specifying the file name.

    Otherwise, you can create a managed folder and then use a python recipe to read the dataset into a data frame and then generate the filename and save the data frame as a CSV file into the folder.

    I hope this helps.
