Bypass CDS view name case conversion in ABAP source code pretty printer

Some colleagues complained that when they consume CDS view in ABAP source code, for example the view below: I_Product

The reason is our team use “Keyword Uppercase” in Pretty Printer setting, and the printer implementation will not differentiate CDS view and normal ABAP variable.

Our requirement is, after Pretty Printer button is clicked, the CDS view name in ABAP source code could remain unchanged. In my example above, it should still be “I_Product”.

They are many ways to achieve this requirement via enhancement, unfortunately the package of pretty printer is configured as non-extensible.

So the only feasible approach is to directly change standard implementation, which is not a good solution but it works.

Open include program LSPPRP04, add a new line in line 167:

CHECK zcl_cds_view_case_tool=>is_cds_view( <abap_token>-lexem ) = abap_false.

The idea is to ignore the LOWER CASE handling of current ABAP token, once it is detected to represent an CDS view.

Test again：before Pretty Printer is clicked, the red line represents the name to be converted, the blue line for CDS view name which will not be touched:

After clicked, it works as expected.
