Hi Omkar,
   Trnasformations providing the mapping between Sorce fields( datasource to  data target).  only map the structures..
<b>Transformations:</b>----
-->Trsnsformations are used to create mappings between two BI Objects and to
transform data from BI Source(From where) to BI Target .
-->You can create One-One Mappings between source and target in BI
-->In transformations Source is : DataSource, InfoSource, DataStore object,
InfoCube, InfoObject and InfoSet
-->Target is: InfoSource, InfoObject, DataStore object and InfoCube.
-->Transformations replaces the transfer and update rules.It's like creating transfer
rules and update rules.Through these rules/mappings/transformations, the
system is going to transform data from Source to Target.
  but DTP  means.. the data loading procedure will be  done with this step..
<b>DTP :</b>
   DTP is used to transfer data from PSA to the infoprovider.
The data transfer process can also be used to control data distribution from a BI system into any target outside of the BI system. For this purpose, a data transfer process with an open hub destination is used as the target.
       Since Deltas are now based on request from PSA ,you can have multiple datatargets pulling data with same selection criteria from same datasource(ECC) with INITS/DELTA,not possible earlier.
