Dynamics NAV - LS Retail - Data Director - Could not receive file. Could not send header.

This happens when the data file being sent to the terminal is too large.

• To resolve this
• Set the compression mode on the job to 7Zip
• In the Data Director Configuration for hte head office, set the 7zip file size to 10
• Save the DD config
• Restart the DD service

Now, when this job fires, it will use 7-zip compression to compress the file as small as possible (but will take a lot longer to compress)

It will also split the files into 10mb chunks and send each to the terminal before extracting and applying.

This will cause the entire process to take a bit longer, but it will handle the large files eventually with no issues.

Data Director file location for sending
