Diagnosis
The InfoProviders that are assembled together to form a MultiProvidercan work together in pairs as delta InfoProviders.
That means that one of the InfoProviders contains cached data for alogical dataset, and the other InfoProvider contains the (new) datasetdelta, which has yet to be posted in the first InfoProvider.

Procedure
You can create pairs of InfoProviders on the current dialog box (withregards to delta caching).
Before you can create a delta pair, you must ensure that both of theInfoProviders involved support delta caching.
You also have to specify the name of an ABAP delta class. This classmust support the IF_RSD_DELTAPAIR interface.
