ALV-Grid-Error: "Fieldcatalog can not be detected" (translated from german)

[Former Member]

Hi,

I want to print out (on the screen) an internal Table about ALV.

The function "REUSE_ALV_FIELDCATALOG_MERGE" set sy-subrc

at 1, which means "inconsistent_interface".

See below, the three code-snippets!

Thanks a lot!

Here the code, how I use this function:

-

---

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = g_repid

i_internal_tabname = 'IT_TMP'

i_inclname = g_repid

CHANGING

ct_fieldcat = it_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.

............................................................

And here the code for the internal table "IT_TMP":

-

---

First the declaration of a type:

-

---

Data: BEGIN OF besuche ,

kunnr LIKE knvv-kunnr,

name1 LIKE kna1-name1,

kndtyp LIKE kna1-katr7, "Basiskunde / Topkunde

kndtyp_txt LIKE tvk7t-vtext,

bes_termin LIKE zcrm_kundenbesu-kontakt,

bes_art LIKE zcrm_kundenbesu-besuchsart,"1=Vor Ort, 5=NL

bes_art_txt TYPE zcrm_tbart_t-bez,

bzirk LIKE knvv-bzirk,

bztxt LIKE t171t-bztxt,

vtweg LIKE knvv-vtweg,

vttxt LIKE tvtwt-vtext,

vkgrp LIKE zcrm_kundenbesu-verk,

vktxt LIKE tvgrt-bezei,

soll_bes_anz TYPE i,

END OF besuche.

-

---

Second the declaration the standard table:

-

---

it_tmp like standard table of besuche.

Hi

try this:

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = g_repid

i_internal_tabname = 'BESUCHE'

i_inclname = g_repid

CHANGING

ct_fieldcat = it_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.

WT_FIELDCAT-TABNAME = 'IT_TMP'.

MODIFY IT_FIELDCAT FROM WT_FIELDCAT TRANSPORTING TABNAME WHERE TABNAME = 'BESUCHE'.

This syntax is rather picky, I know that header lines are obselete, but in this case with this older technology, I believe it may be required. Try adding the HEADER LINE extension to your internal table declaration.

data:  it_tmp like standard table of besuche WITH HEADER LINE.

Hi

Perhaps it's stupid, but have you filled the variable <b>G_REPID</b> ?

<b>G_REPID = SY-REPID.</b>

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_program_name = g_repid

Thank you all very much! You're so great!

All three hints together were the solution!

It works....thanks a lot!

Excellent, if working now, make sure max gets some points and mark this thread as solved. Thanks.
