I tried exactly what you do and it works.

Is the file that you're trying to open maybe an existing one and it's a 0-byte file?

Do you have access rights in the folder where you are trying to write?

Hi Bjarne,

Appeon didn’t modify the FileWrite function in PB 2017 / 2019. It is the same as SAP PB 12.6.

For the FileWrite function, you can refer to the link below for more details:

https://docs.appeon.com/appeon_online_help/pb2019r2/powerscript_reference/ch10s177.html

FileWrite is maintained for backward compatibility. Use the FileWriteEx function for new development.

If the file was opened in text mode, FileWrite returns -1. Use FileWriteEx to write to files in text mode.

https://docs.appeon.com/appeon_online_help/pb2019r2/powerscript_reference/ch10s172.html

The mode in which you open a file determines the behavior of the functions used to read and write to a file. There are two functions that read data from a file: FileRead and FileReadEx, and two functions that write data to a file: FileWrite and FileWriteEx. FileRead and FileWrite have limitations on the amount of data that can be read or written and are maintained for backward compatibility. They do not support text mode.

So，We recommend you to use FileWriteEx function.

Regards,

Ken

Hi Bjarne;

   No, the FileWrite() command is not deprecated. In fact, its the only way to write super large files or write data in "chunks" whereas the FileWriteEX() command only supports an "All or Nothing" approach. The same for the FileReadEX() command. Sometimes you need a more granular control over reading & writing. So the older variants of the read & write will always have to be supported (IMHO).

  Please open a Support Ticket for this issue if its reproducible.

in 2019R2 with filewrite() and fileopen as:

FileOpen(ls_path_doc, LineMode!, Write!, LockWrite!, Append!)

 FileOpen(ls_path_doc, LineMode!, Write!, LockWrite!, Replace!)

with no problems

have not tried with textmode
