If DataSetProvider and ClientDataSet correctly in the same window then save,
If put DataSetProvider DataModule cannot update, complains, what reason be
I get so, during the period of design
ClientDataSet. ProviderName:=DMCON. DataSetProvider1;
Save time
CDS. AppServer. AS_ApplyUpdates (' DMCON. DataSetProvider1, CDS, Delta, 0, ErrorCount, OwnerData);
DMCON is DataModule
