Hi Varaprasad,
The DataStore object has the characteristic InfoObjec 0RECORDMODE (record mode). You can use the record mode to control the delta logic supplied be the application. The characteristic infoObject '0RECORDMODE' in the DataStore object controls whether the records are added, overwritten or even deleted. It determines how a record is updated in the delta process, the delta process itself being determined by the DataSource.
The record mode now describes the type of change that a data record contains. The difference between the various delta processes is that each supports only a subset of the seven possible characteristic values. If a DataSource implements a delta process that uses several characteristic values, the field ROCANCEL (in which the record mode is saved) is automatically part of the DataSource. This field for the DataSource is assigned to the InfoObject 0RECORDMODE in the BI system.

' ': The record provides an after image. The status of the record is transferred after it has been
changed, or after data has been added.
'X': The record provides a before image. The status of the record is transferred before it has been changed or deleted. All attributes for the record that can be aggregated (key figures) must be transferred with a reversed plus/minus sign. These records are ignored in a non-additive (overwriting) update of a DataStore object. The before image complements the after image.
'A': The record provides an additive image. This provides the record with differences for all the numeric values are available. The record can be updated to an InfoCube without restrictions, but requires an additive update to be made to a DataStore object.
'D': The record must be deleted. Only the key is transferred. This record (and therefore the DataSource too) can only be updated to a DataStore object.
'R': The record provides a reverse image. The content of this record is equivalent to a before image. The only difference occurs when updating a DataStore object: An existing record with the same key is deleted.
'N': The record provides a new image. The content of this record is equivalent to an after image without a before image. A new image should be transferred instead of an after image when a record is created. The new image complements the reverse image.
Regrads,
