Unable to upload attachment on Catalog item request as End User on portal

[Subalakshmi P2]

I have a catalog item variable of type "attachment". I am able to upload the attachments and submit the request.
But end users with no role is unable to upload any attachment.

yes, they can see all the variables. When they click upload, choose file pop up opens, and when they select the file. Nothing happens, just the pop up is closed. But the file is not uploaded.

Hi @Subalakshmi P2 

Check the ACL role given in your Create ACL on sys_attachment.

OOB , snc_internal role ( which typically end user is having) can create attachment But for your instance it seems it has been customized.
