Hi Sangram,
Looking at the CustomerPostalAddressEntity I see its main DS is another entity (DirPartyLocationPostalAddressV2Entity), which in turn has a third entity as its main DS (LogisticsPostalAddressBaseEntity).
You need to filter by the LogisticsPostalAddress modified date.
But the problem here is that only the last entity (LogisticsPostalAddressBaseEntity) has a reference to the LogisticsPostalAddress table.
So, to achieve what you want you will need to add the LogisticsPostalAddress modified date to the LogisticsPostalAddressBaseEntity, then to the DirPartyLocationPostalAddressV2Entity and finally to your entity (in this case you could use the out of the box entity, no need to duplicate it).
You can add fields to existing entities through extension, the only thing is that you need to manually add the same field to the corresponding staging table through another extension.
After adding the field to the final entity you can use it to filter the entity on the data project itself, using the SysQueryRangeUtil class.
For example, to filter only records modified yesterday you could use the following range:
(day(-1))
Take a look at the following documentation for more informations on advanced filtering:
