Local structure - FIELDCAT - REUSE_ALV_FIELDCATALOG_MERGE

[vitorssan]

Hello guys, good afternoon.
I'm new and trying to adapt a few programs previously made using factory to alv_grid_display and can't find the reason why isn't my fieldcatalog recognized.

I defined a local structure and used an include to declare;
Also defined lt_fieldcat as slis_t_fieldcat_alv
already have a local table named lt_alv, "LIKE TABLE OF" my structure "lt_foralv" filled correctly through the loop

but I get this error: Field catalog not found

I don't know if anyone has experienced similar problem, but everything I found was fixed defining the structure inside the include.

Can someone help? Thank you very much.=======================================================<br>

DATA: lt_fieldcat TYPE slis_t_fieldcat_alv. 
---Content of INCLUDE "zlt_foralv"---
DATA: BEGIN OF lt_foralv OCCURS 0, 
Name LIKE KNA1-MCOD1, 
Surname LIKE KNA1-MCOD2, 
Country LIKE KNA1-LAND1, 
City LIKE KNA1-ORT01, 
Postal_Code LIKE KNA1-PSTLZ.
DATA END OF lt_foralv.

DATA: lt_alv LIKE TABLE OF lt_foralv.
---------------------------
" Then I used gui_upload method to fill a local table, splitted its lines, 
made a loop in its work area, and apped to lt_alv.

" lt_alv is correctly filled in debbug (all columns are setted as the structure,
 all lines are inserted in lt_alv from csv).

To avoid the popup with the text "Field catalog not found", while running REUSE_ALV_FIELDCATALOG_MERGE, indicate the names in upper case, and indicate the program name too.

      END OF lt_foralv.

Sandra, thanks for your reply.
I've changed it but still doesn't work.

"Field catalog not found Message no.0K530
Diagnosis The field catalog cannot be determined because the output table structure name was not specified."

I got this error while it's processing build_fieldcat perform, so it's probably related to the structure, right? I know if I prepare a structure it's gonna work, but declaring a local structure should work, shouldn't it?

Perhaps the way I filled the internal table is the problem:

DATA: wa_guiupload TYPE string.
DATA: wa_guiupload2 LIKE LINE OF lt_alv.

LOOP AT lt_guiupload INTO wa_guiupload. 
SPLIT wa_guiupload AT ';' INTO 
wa_guiupload2-Name 
wa_guiupload2-Surname 
wa_guiupload2-Country 
wa_guiupload2-City 
wa_guiupload2-Postal_Code. 
APPEND wa_guiupload2 TO lt_alv.
ENDLOOP.

The parameter I_PROGRAM_NAME was missing in your program. Answer fixed.

Thanks for the tips. I've fixed the post. I think it's correct now.
