ALV: Converting fieldcatalog to create internal table

[Thomas1]

Hi all,

when displaying internal tables using ALV I have to provide a fieldcatalog of type SLIS_FIELDCAT_ALV

while I can create a dynamic internal table using a call to method CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE where I have to provide the fieldcatalog with type LVC_S_FCAT.

Does any one know of a method or function module which allows to convert a structure SLIS_FIELDCAT_ALV into LVC_S_FCAT? A simple move-corresponding does not work as the corresponding fields have different names.

Thanks & regards,

Thomas

Hi,

If you are displaying a list using cl_gui_alv_grid class, the field catalogue needs to be of type lvc_t_fcat anyways.

so I would suggest you create the create the field catalog as lvc_t_fcat at first place instead of creating it as SLIS_FIELDCAT_ALV.

hi,

Here is the example . Clearly explained. Have a look.

Hi,

Try using FM REUSE_ALV_GRID_DISPLAY_LVC to display ALV data instead of using FM REUSE_ALV_GRID_DISPLAY.

'REUSE_ALV_GRID_DISPLAY' is for the SLIS type pool.

'REUSE_ALV_GRID_DISPLAY_LVC' is for the LVC type pool which of course has a better functionality.

Hope this helps.

Thanks,

(Sorry, a little late)

To convert between the two format ALV and LVC use :

LVC_TRANSFER_FROM_SLIS
LVC_TRANSFER_TO_SLIS
