The implementation of the integration of the barcode software system and the ERP system puts forward higher requirements for the real-time and accuracy of information in the sales, production and logistics processes. However, to exert the powerful performance of ERP, an efficient execution system is required for planning and The actual production operations are coordinated and managed, and the implementation status of the plan is tracked and fed back in time. After the barcode system is integrated with the ERP system, the accuracy and efficiency of data entry can be greatly improved, especially the accurate and refined management of production management, barcode warehouse management, and sales tracking management links. The barcode management system is in most parts The industry can manage a single product, which makes up for the deficiencies of the ERP system’s document management and batch management methods.
At present, the barcode generation and reading technology is quite mature. The key point of implementing barcode application in the ERP system is how to integrate it with the original ERP system. With years of experience in the implementation of barcode management systems, Hexin Technology provides perfect ERP barcode system integration solutions for the majority of factory manufacturing customers.
1. Why does the ERP system need to be integrated with the barcode software system?
The ERP system is composed of subsystems such as production management, financial management, personnel management, sales and customer relationship management, and decision support. Any ERP system requires a large amount of data input. Only on the premise of getting timely, effective and correct input, the ERP system In order to truly play a role in management and decision-making support for the enterprise. ERP can share correct data across the enterprise, greatly improving productivity. However, the impact of incorrect data entry will also spread to every corner of the enterprise, and may eventually lead to serious management decision errors.
This dependence on input data has become an important issue in the implementation of ERP systems. At present, the most effective solution is still automatic identification technology, especially barcode technology. The barcode technology represented by various one-dimensional codes is already a highly mature technology and has been widely used in manufacturing and commercial sales. After entering the 1990s, barcode technology has given new vitality. Two-dimensional barcode technologies such as PDF417 and QR have the characteristics of large capacity, high error correction rate, and high resistance to damage.
2. What information in the ERP system needs to interact with the barcode software system?
(1) Material information: the attribute information of the material (parts, components, materials), such as the name, code, material code, material, price, etc. of the parts. Generally speaking, each material (parts, parts, Parts and materials) will have a unique code.
(2) Document information: that is, the incoming order number, the outgoing order number, the inventory order number, the transfer order number, etc. The order number information has a corresponding relationship with the material information.
The above two types of information are the basic data required by the ERP system, as well as the basis for its production management, cost management, etc., and these two types of information are also the content of the basic data management of the bar code system.
How does the barcode software system and the ERP system carry out the above data docking?
3. The form of interface between barcode software system and ERP system
Through years of project implementation experience, Hexin Technology has concluded that there are three main types of interface forms between the barcode software system and the ERP system:
1. Active
Active interface, barcode software system writes the information required by ERP directly into the database of ERP system. This method requires a detailed understanding of the internal database structure of the ERP system, and the ERP system allows the barcode system to write data into it (that is, it has the right to write). Generally speaking, the active interface form is generally used in custom-developed or self-developed ERP systems. In this case, the database structure of the ERP system is required to be clear, and what data verification should be performed when entering data in the ERP system It is clear that when the barcode system writes data to the ERP system, it also follows the data verification specifications of the ERP system, and writes the required material information and bill information into the ERP system one by one to ensure the accuracy and effectiveness of the data sex.
With the active interface form, the synchronization of information in the barcode software system and the ERP system is better; but there are certain problems in security. Generally, this method is not recommended for large-scale ERP systems such as BAAN, ORACLE, SAP, etc.
2. Passive
In the passive interface, the ERP system reads the required data from the barcode software system and writes it into its own database. There are two ways for the passive type:
Fully passive: that is, the barcode system completely discloses its database structure for expressing and storing information. When reading the information, the ERP system judges which information is added, which is modified, and which has been deleted.
Semi-passive: In addition to disclosing its database structure, the barcode system also provides some handshake signals to be stored separately in the handshake signal table. The handshake information indicates which information has been updated, so that the ERP system reads the information in the barcode system according to the handshake The signal table is used to read part of the information that has been changed in the bar code system, and it is not necessary to read all of it once, which can increase the speed of interface processing.
With the passive interface form, the synchronization between the barcode software system and the ERP system is also better, and the security is stronger than the active one. Generally, it is more appropriate for the ERP software provider to complete the interface work, which is suitable for self-developed ERP systems.
3. Intermediate
In the intermediate interface method, the barcode software system generates intermediate files or intermediate data tables from the information required by the ERP system, and the ERP system directly reads the information in the intermediate files or intermediate tables and writes them into the database. This method requires the barcode system and ERP Both parties do some development work.
What needs to be put forward in particular is: how to ensure the consistency of the barcode system and the ERP information by using the intermediate method. There are two commonly used methods. One is guaranteed by the ERP system, that is, the barcode system periodically writes the three types of information required by the ERP system in an intermediate file or data table. Some information is analyzed and compared to determine which is new, which is modified, and which is deleted, and finally the updated information is written into the ERP system.
The other is that when the barcode software system generates the intermediate file or data table, it compares with the existing data in the ERP system to determine which data has been updated, and writes the updated data into the intermediate file or data table; ERP system Read the data in the intermediate file or data table and write it directly into your own database. This method requires the ERP system to export the data in its database before the barcode system writes the intermediate file for comparison with the barcode system.
The intermediate interface is a more commonly used method. In this way, the barcode software system and the ERP system are relatively independent. The interface does not involve the internal structure of the two parties, and the responsibilities of the interface are also clear, and the security of the data is also guaranteed; The problem is that the data synchronization between the two systems is slightly worse, but as long as the time for reading and writing intermediate files or data tables is reasonably specified, the synchronization of the data will not affect the use.
These three methods of interface between ERP system and barcode software system have their own advantages and disadvantages, and can be selected according to the specific situation of the enterprise.
