Remarks on the report:

dp Gas is the pressure loss in the gas path (nominal)
dp Dampf is the pressure loss in the steam path (nominal)
K*A(n) corresponds to K*A (nominal)
Alpha G means Alpha Gas, heat-transfer coefficient of gas
Alpha D means Alpha Steam, heat-transfer coefficient of steam
Exp G is the mass flow exponent for gas
Exp D is the mass flow exponent for steam
TQ is the average flue gas temperature (nominal)

Generate sub-report

Select all heat-exchanger components in the water/steam path of the model.
The sequence of selection must be in the direction of flow.
Call the dialog box "Modifying Sub-Reports".
Select the sub-report "Water/Steam - Path, Design Data" and import it in the list of the sub-report.
Enter an extra title, if needed.
Select the sub-report for the design data of the water/steam path and thereafter click the button "Modify" or double-click the sub-report for the design data of the water/steam path.
The dialog box "Edit Sub-Report" opens.
A click on the button "Insert (Select)" the component selected earlier in the cycle is added in the list of the components of the sub-report.
Close the dialog box for the list of the components through the button "Close".
Close the dialog box for modifying the sub-protocol through the button "Close".

The components selected earlier are added in the sub-report in the order in which they were selected.

In case several water/steam paths have to be documented, it can be done in different ways by splitting or merging the lines. As a result, separate sub-reports of this type must be generated for each.
