Documentation
Definition
Source requests of a DTP for which this indicator is set are only transferred once, even if the DTP request is deleted in the target.
Use
If this indicator is set for a delta DTP, a snapshot delta is built.
A scenario of this type may be required if you always want an InfoProvider to contain the most up-to-date data set 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 usually be used to determine the missing delta information (overwrite and creation of delta). If this is not logically possible because, for example, data is deleted in the source without delivering reverse records, you can set this indicator and perform a #snapshot scenario#. Only the most up-to-date request for the 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 during the DTP delta process. When the system determines the delta when a new DTP is generated, these earlier (source) requests are seen as 'already fetched'.
Setting this indicator ensures that the content of the InfoProvider is an exact representation of the source data.
Dependencies
Requests that need to be fetched appear with this indicator in the where-used list of the PSA request, even is they have been deleted. Instead of a traffic light you have a delete indicator.
