ALV with Classes and methods

[Former Member]

Hi All,

Please give the solution for ALV with classes.

Here this code is used for total fields.

Bu ti need only for a group of fields.

Let assume 5 fields.

Please give the solution how to do this i.e for 5 required fields display.

Here i tried by taking gi_bseg with my selected fields.

But it is giving error that i_structure name is not mapping.

TABLES: BSEG.

I guess the reason is BSEG is a cluster table, because of which its throwing the error.

Hi Ravi

It is working when i take

DATA: gi_bseg TYPE STANDARD TABLE OF BSEG.

But when i select some fields like

data : begin of gi_bseg occurs 0,

budat like bseg-budat,

wrbtr like bseg-wrbtr,

end of gi_bseg.

it is giving the error.

HI Prashanth,

create a structure with the fields you want in se11 and then use it in your program..

Hi Prashanth,

If it raises an error when you try to select only a few fields, you could use a crude apporach wherein you collect all data into an internal table. Then transfer all the fileds that you require into a second internal table. Use this table for ALV.

Hi Satish

I tried with ur suggestion but it is not working

Hi Prashanth,

Try to Build your fieldcat manually and pass it , instead of doing that...

then you can able to see the ALV grid Output.

try manually fieldcat for the fields which you want.

Hi prashanth,

build your fieldcatalogue using LVC_FIELDCATALOG_MERGE

and use the fieldcat to display the table when you call the display method..
