Method for XML-based data transmission between SAP systems

A data transmission and data technology, applied in the field of data transmission, can solve problems such as spending a lot of time on joint debugging and testing, data transmission procedures are not smooth, and takes up a lot of work, so as to realize the unification of data interfaces and the definition of shielded interfaces difference, to achieve the effect of unification

Problems solved by technology

When a system business is changed, it will inevitably lead to interface errors between related systems, resulting in unsmooth data transmission procedures before. At this time, it will take a lot of time to modify the interface and joint debugging and testing.
Since there is no unified standard or protocol for the interface definition between systems, when the system that has already been launched changes, the modification and testing of the interface definition will take up a lot of work.

Embodiment Construction

[0036] An XML-based method for data transmission between SAP systems. The method realizes data transmission between SAP systems by encapsulating data content and data format into standard XML, and solves the problem of modifying interface definitions after system changes. Specific steps as follows:

[0037] Step 1. Write the wrapper in ABAP language. Define the interface (in this embodiment, use the interface ZP001_IF_XML definition, but not limited to this name), develop the class implementation class (in this embodiment, use the class ZP001_XML_ITAB definition, but not limited to this name), the methods included in the wrapper are described as follows.

[0038] 1. CONSTRUCTOR: Constructor, to create an XML attribute whose type is if_ixml, which is the final carrier used to store data and internal structure.

[0039] 2. GET_NODE_BY_NAME: According to the node name, the method to get this node.

[0040] 3. CREATE_FOR_ITAB: The method of putting data into the wrapper. Use the static ...

Abstract

The invention discloses a method for XML-based data transmission between SAP systems. Data content and formats are encapsulated in the standard XML so as to realize data transmission between the SAP systems. Architectural differences of system business data can be shielded, and particularly, interface definition differences between the systems can be shielded by application of the standard data type STRING, and thus, data interface unification can be realized. The XML-based method is applicable to data transmission after changing of the two systems.

Description

Technical field [0001] The invention relates to a data transmission method, in particular to a data transmission method between SAP systems based on XML. Background technique [0002] As a large-scale enterprise management software, SAP system is more and more widely used in large group companies and large enterprises in multiple business fields. Many companies have multiple SAP systems, and data exchange or business operations are required between the systems. Synchronization etc. [0003] In an ecological environment where multiple SAP systems are deployed, data transmission is required between these SAP systems. When a system service is sent and changed, it will inevitably lead to interface errors between related systems, leading to unsmooth previous data transmission procedures, and it takes a lot of time to modify the interface and joint debugging and testing. Since there is no uniform standard or agreement for interface definitions between systems, when the systems that hav...
