When you compare units outside IBM® Rational® Rhapsody®,
the units must be of the same type.
Procedure
- To be certain you are comparing units of
the same type, check the file extensions. They must be the same. For
example, you can compare a project (.rpy file) only
to another (.rpy) project, but not with a component
(.cmp file). For more information, see Developing in parallel with Rational Rhapsody DiffMerge.
- From the Rational Rhapsody DiffMerge menu
bar, open the Select Files window. Choose .
Note that
the units might have different names.
- In the Left side Rhapsody unit field,
type the name including the path of the first unit or browse to the
location. This file will be referenced as the "Left" in the comparison
results.
- In the Right side Rhapsody unit field,
type the name including the path of the second unit or browse to the
location. This file will be referenced as the "Right" in the comparison
results.
- Select the Compare with descendants check
box if you want to include the nested units for these two units
in the comparison.
- Select the Base‑aware mode check
box if you want to browse to select the base or parent unit of the
two previously selected files to use as the base‑line for the comparison.
If you use this third unit in the comparison, this creates a base‑aware
comparison. For more information about this type of comparison, see Results displayed for compare of three units. For more
information about this report, you might also want to see Generating difference reports. Displaying
base‑aware information in this report is controlled by several DiffReport preferences category preferences.
- Click OK. Rational Rhapsody DiffMerge compares
the selected units and displays the results. See Examining filenames of units being compared.
