I want to import a csv file from legacy system which does not have any unique column or even combination of columns is also not unique. I am getting following error "File contains duplicate rows, cannot insert data into staging due to unique key violation." But when I put any unique column , I can do import successfully . So it is limitation in DMF that we cannot import such type of files which does not have unique keys?
I also tried using "FileUploadTemporaryStorageResult" to import the file which worked well in case of manually . But when tried to implement same in Batch using "SysOperation" framework , generated parameter four type of inputs.
Let me know if someone implemented CSV file import using SysOperation framework or even in Batch in Dynamics 365 Finance and operation ?
