Answer 1

A slightly dirty solution:
Use SAP functions for reading from CDHEADER and CDPOS tables [with enough filters such that you extract minimum records possible] to read changes to MARA table fields since last run of your program. Use this information to update your ZTABLE. I would recommend having a table maintainance generator on ZTABLE. The actual update should be by a BDC by calling transaction SM30 for ZTABLE maintainance. Now the program may be set up as a batch job running 1ce an hour. You get updates to the extent of 1 hour latency.
Alternatively, you may look if an opportunistic BADI / user Exit is there alongside MM01/02 transactions - assuming the latter are the only ones updating MARA. In this BADI you may write the code to update ZTABLE- again, look to do it by BDC call transaction sm30 to maintain ZTable. To lighten up the code -load on BADI you may simply raise a custom event and move on. You will configure a job that runs your program when that particular event is raised. This will need the 'burden' of figuring out the changes, though.
An elegant way would be to fire a MATMAS fIDOC for every change to Material, capture that and turn back the changes to ZTABLE. This will facilitate the delta load.
