In the last blog post we drilled deep into the GS1-128 labeling. In this post, we will go through the steps on how to setup WMS to enable GS1-128 printing.
1. LPN Setup: GS1-128 label requires an LPN to be generated as per SSCC standards. An SSCC-18 number is a unique 18-digit license plate number that is generated as per specific UCC standards. Therefore to generate GS1-128 label requires this 18 digit number to be generated.
2. Create GS1-128 label layout (see sample label) in a label designing software. In this example, the number following (00) is the SSCC-18 number. Whereas (00) is the application identifier. Please note that application identifier should appear in the human readable format as “(00)”. However in actual barcode the application identifier should be encoded as “00” (i.e. without brackets). The variable following the “00” is the 18-digit LPN number from WMS.
3. To auto-generate LPN using SSCC-18 standard, the following setup is needed in org parameters form:
4. Note: As per GS1/UCC standards, application identifier (00) is not part of the SSCC-18 data structure and need not be transmitted as a prefix for LPN in ASNs. However there are customers who require incoming ASN must have LPNs with 20-digit container reference. In this case the 20 digit number consists of 18 digit-SSCC number prefixed with SSCC application identifier “00”. Prefixing “00” to SSCC number will not change the check digit of SSCC. If a customer requires 20-digit container reference, a prefix of “00” can be added in either the label printing software or the prefix of “00” can be added to the extension digit. The setup in this case may look like:
Sometimes customers also enforce a range of container serials for certain warehouses e.g. W1 container serials start with 1, W2 with 2 etc. in such as case, the leading digit from the container serial can be removed and suffixed to LPN prefix:
This way, W1 will always generate LPNs in SSCC18 format that is distinct from W2.
5. Create a label format “UCC128” for type “Shipping Content”. Include fields such as LPN (SSCC-18), Ship to address, PO, Ship from address, etc. as shown in the figure above. You can make this the default label format for “Shipping Content” label.
6. Select a valid printer.
7. Assign “Shipping Content” label to business flow “pick drop” (you may use other business flows like packing workbench, ship confirm or pick load)
