Our PO30 receipts go to MSCM for tracking and delivery. Below is from a Lawson KB doc that I had from when we first set this up 5 or 6 years ago.
If Header level package tracking is defined for your PO Company (PO01),
when a PO is received on either on the handheld or directly on PO30, upon
release of the receipt, a file is placed in the Arrival Directory
($LAWDIR/prodline/work/ARRIVAL).
These files are brought over to the MSCM application via the potrack
scheduler. When the receipt file is transferred from the Arrival
directory successfully, the file will be deleted from the ARRIVAL
directory and the Delivery Document for the PO receipt will be available
to print via MSCM. If the receipt file is not transferred successfully,
there will be a .err file in the ARRIVAL directory.
For instances where MSCM is running on a Windows Server and the Lawson
Back Office is Unix - Samba is the suggested method for sharing the files.
In the mscm.filter.properties file, the definition for the
potrack.sync.dir needs to have unix slashes (Example:
//lawson.com/potrack).
