Doubt regarding triggering Change pointer for Customer master field
We have a project requirement (which makes use of iDOC ) as below:(only sufficient part of requirement is mentioned)
1) Initially(before the project goes live) we need to send all active customers and material belonging to a paricular sales org to SAP PI.
2) After wards data will be send based on change pointers, i.e, everytime the user changes the Mobile number of the customer in the customer master, it should trigger a change poiner.
As we have only basic knowledge regarding iDOC and change pointers , can someone throw some light on how this is to be done?
Please help .
Thanks in advance,
