Change Pointer Concept

SAP maintains change documents for several objects in the system, such as materials, customers, invoices, and bank data, to provide an audit trail for changes made to an object. A change document object represents a set of tables for which changes are recorded. For example, the change document for the material master is named MATERIAL and it contains the various tables of the material master object, such as MARA and MARC. When an application transaction makes changes to an object, the application writes change documents, which are stored in the CDHDR and CDPOS tables for each change made to an object.

We can see change documents object and their respective table by using transaction SCDO (not zero :). I will discuss on how to create a custom change document in other blog.

We can use change pointer to generate IDOC, and below is the configuration required to make it happen.

1. Activate change pointer globally using transaction BD61.

2. Enable change pointer for a message type using transaction BD50

3. Specify the Fields for Which Change Pointers Are to Be Written using transaction BD52

4. Executing Program RBDMIDOC to Process Change Pointers

Life is beautiful! Let's make it meaningful and colorful!
