Title
Logical Database HV0J for Contract Reporting

Purpose
Logical database (LDB) HV0J provides a standard interface for variousqueries within contract reporting. This allows corrections and tuningof database accesses to be performed at various locations. Individualreports that use the LDB therefore no longer have to transmitindividual SELECT instructions.

Integration
Report RJHABS16 that performs a similar function to RJHABS10 useslogical database HV0J. This report can be used as an example forcustomer reports that are based on this LDB.

Selection
The JHV_RJHABS10 node is only used for selection purposes. Theselection screen provided by the LDB does not contain fields from othernodes.

Output
Reports should not contain any GET JHV_RJHABS10 since this structure isnot filled by the LDB.
The JHTVKO node is the highest node in the hierarchy for which the LDBsupplies data. GET events are admissible for this node and alllower-level nodes in the report.

Example
RJHABS16 can be used as an example for the use of the logical databasein a report.
