Which is better or 'standard' option for a Delta DTP request

Question

Hi folks,
            I am creating a delta DTP for loading HR Payroll data. While creating the DTP I see two options
a) Only Get Delta once
b) Get all new data request by request
which is a better option if I have a lot of records to upload for every delta upload.
Points waiting to be given to you...
Thanks
Sunil

Answer 1

U should go with Get all new data request by request
i. With Only Get Delta Once, define if the source requests should be transferred only once.
Setting this flag ensures that the content of the InfoProvider is an exact representation of the source data.
A scenario of this type may be required if you always want an InfoProvider to contain the most recent data for a query, but technical reasons prevent the DataSource on which it is based from delivering a delta (new, changed or deleted data records). For this type of DataSource, the current data set for the required selection can only be transferred using a full update.
In this case, a DataStore object cannot normally be used to determine the missing delta information (overwrite and create delta). If this is not logically possible because, for example, data is deleted in the source without delivering reverse records, you can set this flag and perform a snapshot scenario. Only the most recent request for this DataSource is retained in the InfoProvider. Earlier requests for the DataSource are deleted from the (target) InfoProvider before a new one is requested (this is done by a process in a process chain, for example). They are not transferred again by the DTP delta process. When the system determines the delta when a new DTP request is generated, these earlier (source) requests are considered to have been retrieved
ii. Define if you want to Get All New Data in Source Request by Request.
Since a DTP bundles all transfer-relevant requests from the source, it sometimes generates large requests. If you do not want to use a single DTP request to transfer the dataset from the source because the dataset is too large, you can set the Get All New Data in Source Request by Request flag. This specifies that you want the DTP to read only one request from the source at a time. Once processing is completed, the DTP request checks for further new requests in the source. If it finds any, it automatically creates an additional DTP request.
