Multiple Layouts

Former Member — Mon, 12 Jan 2009 07:34:30 GMT

Dear friends,

I have a ALV report with options of Hierarchial list display and Grid Display. But the problem arises when selecting the layout in the selection screen.

How to handle layout when there are multiple list display options, kindly suggest.

Regards,

Praveen Lobo

Hi Praveen,

To handle different layouts in ALV grid display, you can use the concept of variants.

Use it this way if using FM REUSE_ALV_GRID_DISPLAY:-


*&---------------------------------------------------------------------*

*&---------------------------------------------------------------------*
TYPE-POOLS : slis.

Hello,

I already used this options of variant. But the problem arises when i use multiple list display i.e. Hierarchial and Grid Display.

The report not able to determine which variant belongs to which list display and causing error.
