ALV

Former Member — Sat, 24 Nov 2007 19:02:47 GMT

Hello Everyone,

I am just testing the following code...to practice on ALV. For some reason, I am not able to see the output. It gives out a memory dump, if I try to run this. After some troubleshooting...found that it gives the memory dump when I call the function...REUSE_ALV_GRID_DISPLAY. Also found that if I use some data dictionary structure for my field catalog...it does not give me this memory dump. Could anyone please help me on this. What I am doing in creating fieldcatalog, that I should not be doing??

I do have some confusion about the field catalog function as well. If I use the function: REUSE_ALV_FIELDCATALOG_MERGE...do I still need to populate my field catalog internal table with the field names or this function should do it for me. I did check the field catalog internal table after calling this function, but it does not show any field names in it.

Thanks for the great help...in advanced.

type-pools : slis.

tables sflight.

DATA WS_REPNAME LIKE SY-REPID.

WS_REPNAME = SY-REPID.

data : itab1 type slis_t_fieldcat_alv.

data : wa type slis_fieldcat_alv.

CARRID like sflight-carrid,

FLDATE like sflight-fldate,

CURRENCY like sflight-currency,

end of itab.

Hi,

While building your fieldcatalog you should make sure that all the field names should be in upper case. example as below :

wa-col_pos = 1.
wa-fieldname = 'CARRID'. "Changed carrid to CARRID
wa-seltext_s = 'Airline id'.
wa-tabname = 'itab'.
append wa to itab1.

wa-col_pos = 2.
wa-fieldname = 'CONNID'. "Changed connid to CONNID
wa-seltext_s = 'Connection id'.
wa-tabname = 'itab'.
append wa to itab1.

You need to change all the fieldname to upper case, then you can overcome this issue.

Thanks,

Sriram Ponna.

Hello

The sample report <b>ZUS_SDN_FIELDCATALOG_1</b> in thread

demonstrates how to use internal data definitions (instead of DDIC structures) for generating the fieldcatalog.

However, I highly disregard to use internal data definitions.

Hello,

Thanks for the replies. I did what you guys suggested...did little bit more research on it... but still getting the memory dump. I guess it might be this minisap version...I just downloaded couple of days ago, might have some issues...Well I will try this on with my other pc....and see how things are....thanks for the great help! Appreciate your input.

Hello All,

Thanks for the great help! Well I found the solution to my runtime errors. Apparently I needed to pass the table name with square brackets while calling the GRID DISPLAY function...like this:

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

IT_FIELDCAT = ITAB1 <--- instead of this, I should pass the table as ITAB1[]

TABLES

T_OUTTAB = ITAB. <---and this one as well...ITAB[]

that fixed my problem.

Thanks for all those who helped me.
