How do I construct a single variable value in ABAP 750?

jrgkraus — Wed, 17 Apr 2019 08:33:49 GMT

Every now and then I happen to be in need of the construction of a single variable value. The VALUE operator does it only for structures and tables, so I use a workaround with EXACT. See the example:

r_success = exact abap_bool(
  let data_necessary = get_data_necessary( i_input ) in
  do_booking( data_necessary ) ).

Now, syntax check says, this is a redundant conversion and I have to use a pragma to hide this. Isn't there a possibility to construct only one single variable similar to VALUE for structures without ugly workarounds?

Hello Jörg,

not sure I got your point, but in this context I would use xsdbool( ).

This does not work. LET is not possible within XSDBOOL( )

Hello Jörg,

can the CONV operater help in this question?

The ABAP Help says:

"The conversion operator CONV closes the gap where the value operator VALUE cannot be used to construct values for elementary data objects except for the initial value."

Regards,

Philipp

You can use CONV instead of EXACT to get rid of the warning.

This is the solution with conv

    data(success) = conv abap_bool(
      let data_necessary = get_data_necessary( `input` ) in
      do_booking( data_necessary ) ).
