Capture the material master changes during the update

Hello,

My requirement is to run some program that will evaluate the changes done in the material master and then execute some other program, based upon whether these changes satisfy some criteria.

Now, the issue is, we want to capture the material master changes after the database updates and we are planning to use the MATERIAL_WRITE_DOCUMENT for that purpose, but I could not find any BADI/user exit, which could be used to implement the custom code.

Note - We want to run this program online at the time of changes in material master, so we don't want to read the CDPOS and CDHDR tables.
