SRM Master Data Replication in SRM 7.0

We have uploaded the initial data from ECC. Whenever I change existing material master data or create a new material the same is not being replicated to SRM. Do I need to run any batch job

1) for changes to existing master data

2) creation of new master data

3) creation of new material group.

Intitial Data Load (R3AS)

Delta Data Load (New materials created in ECC)

Change in existing material masters

Change in existing material groups

Change in existing service masters

Thanks
