Sap-abap- how to transfer material master data, supplier master data, work orders, purchase orders and other information to external systems in real time - implicit enhancement.

Want to transmit all kinds of master data to external systems in real time , It must be after creating and modifying master data , Trigger enhancement on save , Then call the interface. , But the problem is that the basic first, second and third generation enhancements rarely reserve such enhancements , The fourth generation enhancement is used here .

To ensure that all checkpoints have passed , Our idea is to find the statement with the new database in the standard code COMMIT WORK, After updating the database table , But make enhancements before exiting . Take the production order as an example .

1. Create production order according to the front desk , Step by step tracking , Find the update database statement （ This step is the most time consuming , It can also be used. Code scan search COMMIT as well as View program name To quickly locate ）, You can also set the breakpoint lookup location

 

The code of the production order update database statement I found is shown in the figure below

 2. After looking for updates , Implicit enhancement points before exit

 

  Then these places with arrows can be implicitly enhanced

  Then click the line with small arrow with the mouse pointer and implement it according to the following figure , This ensures that all the standard checks have been passed , Just look up the table and you can get the data

 **********

Also share some other places where the master data update table

Purchase order

  Supplier master data

  Material master data

Create customer master data

Finally, let's talk about where implicit enhancement points will appear

Except that it can be used enhance - point and enhance - section Explicitly created enhancement options ,ABAP Implicit enhancement options also exist in the following places in the program :

• In the executable program 、 Function groups 、 Module pool 、 After the subroutine pool and the last line of source code that contains the program .

• Before the first and after the last line of the procedure implementation ( After the introductory statement and END The statement before )

• Before and after the first line of the source plug-in ( stay ENHANCEMENT And after ENDENHANCEMENT Before )

• At the end of the visibility area of the local class declaration section

• At the end of the parameter list with the same name at the local method declaration

• In the structure definition ,BEGIN OF and END OF With END OF Before the addition statement

Implicit enhancements are extremely powerful , But it is also the most difficult to use , It requires developers to have a good understanding of the source code before it can be used
