Description
General procedure to read data from the database into the class dataset.
The data is stored into the temp-tables referred by a handle in tFcDynRel.
Parameters
| tDynRel | input | temp-table | Description of the data to read. |
| ihClass | input | handle | Handle to the class that is using the persistence layer. In most of the cases, this handle will be available in the preprocessor {&TARGETPROCEDURE}. |
| oiReturnStatus | output | integer | |
