Hi

To create the catalog table for ALV grid OO, here you can transfer the name DICTIONARY STRUCTURE and it returns automatically the catalog table arranged on declaration of the table:

call function 'LVC_FIELDCATALOG_MERGE'

EXPORTING

i_structure_name = <DICTIONARY STRUCT>

I_BYPASSING_BUFFER = 'X'

CHANGING

ct_fieldcat = it_grid_fcat.

hi John,

This is a ALV control service modules which is used to generate the field catalog automatically or semi-automatically. You combine structure information of the Data Dictionary with your own structure information and send it to the FM and it will return the field catalog ie the struture that is used to display the final internal table in the form of ALV report.

Check out the link.. This contains good info on this.

Hello max Bianci,

While creating a structure, i need to give a component

which i declared as type dats in program.

How to declare that in structure ?

[Former Member]

hi,

you can declare the field in the structure with reference some dataelement (eg ERDAT) which has data type Dats or you can assign the data element direct types in the table i.e you can give the datatype directly without using data element.

Hope this helps.

Hi

You have to create a field type dats in your ALV structure in the dictionary (trx SE11), if you want the that fm get a your own description you should create a data element with DATS as type (domain) and assign this data element to a field of your alv structure

Hi John,

While building fieldcatalog with <b>containers</b> we use this Function Module LVC_FIELDCATALOG_MERGE , this is similar o REUSE_ALV_FIELDCATALOG_MERGE when using normal ALV FMs

[Former Member]

Hello,

If you use this FM, automatically fieldcatalog will be populated by just passing the structure name.
