Change Pointer Activation

Activate the change pointer in the system by going to BD61

Go to WE81 and create a new Message type: ZMATMAS_AMPL:

Add an entry for ZMATMAS_AMPL in BD50 and activate the change pointer for the same

Goto BD52 and maintain the fields for which the change pointer should get triggered

Now, whenever there will be any changes in those particular fields, changes will get saved in table BDCP2. You can also check CDPOS and CDHDR to get the old value and new value.Use table TBD62 to get the Object ID for the change pointer
