Customizable ALV?

Former Member — Wed, 19 Feb 2014 05:18:25 GMT

Hello everybody,

it is possible to create a ALV dynamiccylly be referenzing to a strukture or a table of the dictionary.

I find it very expensive to maintain the field-catalogue in the coding.

Field can have a color
visible/not visible
editable
etc.

Is there a solution provided to maintain the fieldcatalogue via a customizing table, where the ABAP loops and defines des fieldcatalogue from the customizing-table?

Thanks

Regards

Mario

Hi,

Try with CL_SALV_TABLE class. Search for demo programs in SE38 starting with SALV_DEMO*.

Thanks & Regards

Hi Bala,

sorry, I can't find an ABAP in ALVDEMO* where the ALV is customizable. All Settings are made in the coding.

Hi Mario,

You could have achieved your functionality easily using the class: cl_salv_table. But it does not support 'EDIT' functionality. Please read documentation in SE24 for this class 'cl_salv_table'. It provides an easy example too in the docu.

please refer this doc for displaying dynamic ALV,

Create a structure of the desired fields in SE11, than invoke FM LVC_FIELDCATALOG_MERGE / REUSE_ALV_FIELDCATALOG_MERGE.

Also CL_SALV_TABLE will be able to complete the fieldcat automatically if all the data types in the internal table is standard / is defined in the dictionary. Moreover making ALV OM(CL_SALV_TABLE) is a tiresome process. You can look for examples by having a search in SE38 with parameters SALV_DEMO*

Hello Mario,

You can build Fieldcatalog using the FM " REUSE_ALV_FIELDCATALOG_MERGE".

You can pass either internal table or structure as below and fieldcatalog will be build in the result table.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = c_lv_repid

i_internal_tabname = <Internal table> " pass this incase of internal table

I_STRUCTURE_NAME = <SE11 structure> "Pass this in case of structure which defined in SE11

i_inclname = c_lv_repid

CHANGING

ct_fieldcat = itab_lt_fieldcat

EXCEPTIONS

inconsistent_interface = 1

program_error = 2

OTHERS = 3.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Regards,

Thanga

Hi,

Thank you all. It seems that I have to code it.

I was looking for a ready to use solution which is not available.
