Assisted Ms. Rosell Ordonez on her problem on POS2NAV. As per checking after generating on the sales parser, there is an error prompting "Unable to remote." whenever she tried uploading it on the POS2NAV. Checked her connection. since she is already connected I let her tried uploading again.  After uploading there is another error prompting " Invalid JDA File". I checked on her NAV the POS Payment and all the poll files were already uploaded. I advised her to reject all the uploaded poll file with errors then tried reuploading again. This is now okay.
