  • Внутренние таблицы как источник в SQL запросах

    04, 13, 2021 | 20:58 pm

    В релизе ABAP 7.52 стало возможным использование внутренних таблиц как источника данных в ABAP SQL: [crayon-607a6930c335a117884678/] Существует два сценария выполнения таких запросов: Для выполнения SQL запроса не требуется переноса содержимого внутренней таблицы на уровень СУБД. В таком случае обработка запроса осуществляется непосредственно на сервере приложений, по аналогии с табличным буфером.[…]

  • Динамические журнальные точки

    04, 8, 2021 | 16:52 pm

    В ABAP довольно таки давно существует функционал журнальных точек, который позволяет активировать запись в журнал (в тр. SAAB) определённых данных из программы.

  • AMDP Функции

    04, 3, 2021 | 19:46 pm

    Начиная с релиза ABAP 7.50 у нас появилась возможность создания не только AMDP процедур, но и AMDP функций.

  • Короткая форма VALUE при формировании таблиц

    03, 28, 2021 | 16:07 pm

    У оператора VALUE #( ) при формировании внутренних таблиц есть так называемая короткая форма: [crayon-607a6930c46ca513293527/] Что соответствует следующему полному синтаксису: [crayon-607a6930c46d0119893524/] Таким образом мы можем не указывать все столбцы, если хотим их заполнить на основе столбцов вне внутренних скобок. Удобно использовать для формирования диапазонов: [crayon-607a6930c46d3946993285/] Все что указано за пределами[…]

  • ALV Grid in the nutshell: Field catalog -col_id - ALV control: Column ID

    06, 8, 2020 | 21:47 pm

    ALV Grid in the nutshell: Field catalog -col_id - ALV control: Column ID Column ID is not really a special field in ALV.

    ALV Grid in the nutshell: Field catalog - sp_group - Group key Group key is not widely used but it has nice feature.

  • ALV Grid in the nutshell: Field catalog - domname - Domain name

    04, 18, 2020 | 14:13 pm

    ALV Grid in the nutshell: Field catalog - domname - Domain name You may suspect that setting up a domain name in the field catalog will make some effect on the display, for example in data type, length, lowercase sign,  but it seems that it has no effect in ALV grid.
