EDI For 3PL

A listing of the most commonly used 3PL (Third Party Logistics Provider) EDI transactions.

Terminology

• depositor: a manufacturer, seller or wholesaler that owns the product that need to be stored in warehouse.
• customer: a buyer, consumer or retailer that purchases the product.

3PL Process

In general, third-party warehouses store products for depositor who then instruct the warehouse to ship to other locations. This process, utilizing EDI, generally follows this sequence:

• Depositor transmits production information to warehouse for reference in future communication. This is done using EDI 888 Item Maintenance transaction.
   
• Prior to shipping product to the warehouse, the manufacturer sends a shipment notification to indicate to the warehouse that an order is on its way. This is done using the EDI 943 Warehouse Stock Transfer Shipment Advice transaction. (Note: this ship notice is different from 856, which is for notice of delivery to customer.)
   
• When the shipment arrives, the warehouse confirms this by transmitting an EDI 944 Warehouse Stock Receipt transaction.
   
• The depositor periodically submits an EDI 940 Warehouse Shipping Order to the warehouse. This transaction directs the warehouse to ship product from its stock, usually to customer locations. depositor may also use this transaction to change or cancel the shipping order.
   
• The warehouse confirms shipment of the order using a EDI 945 Warehouse Shipping Advice transaction.
   
• If customer is a business entity, EDI 856 Ship Notice/Manifest transaction is generally required to be transmitted by either the depositor or the warehouse.
   
• Warehouse or depositor may use EDI 947 Warehouse Inventory Adjustment Advice transaction to information each other of a quantity or status change to inventory records.
   
• Warehouse and depositor can utilize EDI 846 Inventory Inquiry/Advice to reconcile the inventory.

X12 EDI Documents

Table below listed the relevant X12 EDI transactions in the order of the transaction number.

X12	Name	Description
846	Inventory Inquiry/Advice	This transaction set can be used in the following ways: for a seller of goods and services to provide inventory information to a prospective purchaser, with no obligation to the purchaser to acquire these goods or services; for a representative of a seller of goods and services to supply inventory information to that seller; for one location to supply another location with inventory information; and for an inquiry as to the availability of inventory with no obligation on the seller of goods and services to reserve that inventory.
856	Ship Notice/Manifest	This transaction is more commonly called the Advance Ship Notice or ASN. It is utilized to electronically communicate the contents of a shipment to another trading partner. It is sent in advance of a shipment arriving at the other trading partner’s facility.
888	Item Maintenance	This transaction set is used to enable a manufacturer, supplier, broker, or agent to provide detailed finished goods product information to a partner in a consumer goods market. This transaction set can be used to provide information about new products or changes in existing product specifications. Price changes will not be sent with this transaction set, but can be sent with the Price Change Transaction Set (879)
940	Warehouse Shipping Order	This transaction set is used to instruct remote warehouses to ship orders. It is commonly used by a depositor, to authorize a warehouse to make a shipment to a customer. The 940 may also be used to confirm a shipment, modify a shipment or cancel a previous shipping order.
943	Warehouse Stock Transfer Shipment Advice	This transaction set is an advance ship notice to a remote warehouse that a transfer shipment has been made to the warehouse. The 943 transaction may also be used by depositor to authorize a warehouse to accept a return from a customer.
944	Warehouse Stock Receipt	This transaction set is an acknowledgement from warehouse to the depositor that its transfer shipment has been received.
945	Warehouse Shipping Advice	This transaction set, also known as Warehouse Shipping Order Confirmation, provides confirmation of a shipment. It is used by warehouse to notify the depositor that a shipment was made.
947	Warehouse Inventory Adjustment Advice	This transaction set is used to inform a warehouse/depositor of a quantity or status change to inventory records. This transaction set provides detail information concerning the internal adjustments which occur between a warehouse and a depositor.
997	Functional Acknowledgment	This transaction set, known as the Functional Acknowledgment or FA, is sent as a response to other EDI transactions received. An EDI 997 serves as a receipt, to acknowledge that an EDI transaction, or a group of transactions, was received by the remote party.

C# to Java–Type System

This is one of the informal discussions with a group undergoing the transition from C# to Java.

Type System

 

C#

The common type system in the .NET Framework supports the following five categories of types: class, delegate, structure(struct), enumeration(enum) and interface.

Except interface type by itself cannot create concrete object, types are further categorized by data type into value type and reference type. A value type holds the data within its own memory allocation. A reference type contains a pointer to another memory location that holds the data. Class and delegate are reference types and struct and enum are value types.

All .Net types except interfaces inherit from ultimate base class System.Object.

All primitive types are structures, which also inherits from System.Object.

.Net Array is a class type.

Java

There are two kinds of types in the Java programming language: primitive types and reference types.

There is also a special null type, the type of the expression null, which has no name. The null reference can always be cast to any reference type. In practice, the programmer can ignore the null type and just pretend that null is merely a special literal that can be of any reference type.

Java primitive type does not inherit from java.lang.Object and Java has no user defined value type. This is a disadvantage over .Net.

Java language specification categorized reference type by how they appear in language structure. But essentially, reference type can be further categorized into class type and interface type.

Java enum is a special class type. This is a big advantage over .Net.

Java has no delegate. Needless to say lamba expression. This is a huge disadvantage. The workaround is to use interface and anonymous class. Example:

public Comp() {
    List<String> foo = new LinkedList<String>();
    Collections.sort( foo, new Comparator<String>() {
        public int compare( String s1, String s2 ) {
            return s1.compareTo( s2 );
        }
    });
}

with many limitations.

Inheritance

Although .Net allows multiple inheritance of classes, C# language allows class to inherit form only one base class and can implement multiple interfaces. Interface can in turn inherit multiple interfaces. Java is same as C# on this.

Misc

C# use sealed keyword to prevent other class from inheriting it. Java uses final keyword.

C# use static keyword to make a class not insatiable. Java has no counterpart for this. The workaround is to use private constructor. Java has complete different use of static modifier of class and we’ll cover in a later session about member class.

The meaning of abstract class is identical in C# and Java

C# to Java–Access Modifiers

This is one of the informal discussions with a group undergoing the transition from C# to Java.

Assembly vs. .Jar File

.Net code need to be packed into an assembly to be useful. Java has no concept of this. Java’s runtime code unit is class file. The closest thing in Java as to the .Net assembly is a .jar file, which is merely a zip of a logically related group of class files. Metadata about the .jar file can also be pack in the .jar file. Hence, java has no version and assembly access scope.

Access Modifiers

 

C#

C# has four access modifiers: public, protected, internal and private.

protected and private modifiers are not applicable to top level types.

protected is only accessible by derived types.

The default access is internal for top level types, public for interface members, and private for everything else.

You can use both internal and protected, which gives you both access.

Java

Java has only three access modifiers: public, protected and private. But when you don’t give an access modifier, it means package access. Package access only allow classes defined in the same package to have access.

protected and private modifiers are not applicable to top level types which is same as .Net

protected gives package access plus accessible by derived classes.

The default is always package access in Java. But bear in mind that any body can define the same package name. So the access control is merely by convention and should be used as a security measure.
