Updating Existing File Attachments During the Attachment Process in JAVADOC EPMDocument Applications

[ozclkonur]

This code performs the file attachment process, but I’m encountering an issue: when I attempt to attach the same file again, it gives a warning saying the file already exists or has been previously attached. In this scenario, the file should be updated if it already exists. I've made some modifications to handle this, but they didn't work. Could you help me with this? Should I delete the existing file first, or is it possible to directly update it?

Hi @ozclkonur,

Write a logic to get all the existing attachments in the list.

Compare the file name what you want to upload with existing list of files.

If any of the file name is matched, delete the file.

Then use the API to upload your file.

I understand, but none of the changes I make within the upload function are taking effect. I change the ID, but it still tries to send the file using the first ID I initially used. I'm not sure if it's an issue with Eclipse, but I'm facing this problem. I've changed the ID 8 times to perform a different operation, yet it still triggers the first ID and attempts to send the initial data.

It keeps showing the following output:

INFO : wt.system.out plm-1 - wt.epm.EPMDocument:114592789
INFO : wt.system.out plm-1 - ---Role Set---
INFO : wt.system.out plm-1 - --Upload Begin--
INFO : wt.system.err plm-1 - (wt.epm.util.EPMResource/266) wt.util.WTException: Content with file name "vns-042754_2ad.pdf" already exists. Cannot add another content with same name.

As I mentioned, I'm changing the ID, but this issue persists.
