Hi ,

I am just learning ALV reporting.

I have an internal table and I have an issue here.

I am getting the output but the only problem is ...I am not getting the heading(field names ) for the output .

Please review my code and let me know if there is anything else I need to add in it..

Hi Ramana,

Put a breakpoint after Fm REUSE_ALV_FIELDCATALOG_MERGE and see if the fieldname are populated in the GT_FIELDCAT. This FM create the field label if those fields are referrend from the dictionary structure.

Yes Atish ,

I see that all the fields are populated in that itab of fieldcat.

Hi Ramana,

Look for the field reptext_ddic, or seltext_l, seltext_m or seltext_s.

These should be filled to show the field label.

Yes Atish , I think you are at the right point of the fieldcat...

please find the fileds populated in that ...

0 | 1 |EBELN |GT_OUTPUT <

0 | 2 |EBELP |GT_OUTPUT <

0 | 4 |MATNR |GT_OUTPUT <

0 | 5 |MAKTX |GT_OUTPUT <

0 | 6 |GERNR |GT_OUTPUT <

0 | 7 |EQUNR |GT_OUTPUT <

_______________________________________________

I see that one field is missing in it ....please see the definition of the iternal table output...

DATA : BEGIN OF gt_output OCCURS 0,

ebeln TYPE ebeln,

ebelp TYPE ebelp,

zucode TYPE zitp01-zucode,

matnr TYPE matnr,

maktx TYPE maktx,

gernr TYPE gernr,

equnr TYPE equnr,

END OF gt_output.

Is there any correction I need to make in this???

Hi Ramana,

First change the defination of

zucode TYPE zitp01-zucode

and refer it to the dataelemnet of the field ZUCODE.

zucode TYPE <dataelement>

Try to define your table like this:

DATA : BEGIN OF gt_output OCCURS 0,
ebeln TYPE ebeln,
ebelp TYPE ebelp,
zucode TYPE zucode,   "<<<
matnr TYPE matnr,
maktx TYPE maktx,
gernr TYPE gernr,
equnr TYPE equnr,
END OF gt_output.

Hi Naimesh & Atish ,

I changed it...

DATA : BEGIN OF gt_output OCCURS 0,

ebeln type ebeln,

ebelp type ebelp,

zucode type zucode,

matnr type matnr,

maktx type maktx,

gernr type sernr,

equnr type equnr,

END OF gt_output.

But it is the same ...

Hi Ramana,

As I told you the field names are poulated only if those fields are referrend from the dictionary structure. That is when you pass the structure name to the FM.

As you are using only 7 fields just create the fieldcatlog in the same way as below for the fields

ls_fieldcat-col_pos = pos.

ls_fieldcat-fieldname = 'UNIT_PRICE'.

ls_fieldcat-tabname = 'GT_DISP_TABLE'.

ls_fieldcat-ref_fieldname = 'DMBTR'.

ls_fieldcat-ref_tabname = 'MSEG'.

ls_fieldcat-reptext_ddic = text-c01.

ls_fieldcat-seltext_l = text-c01.

ls_fieldcat-seltext_m = text-c01.

ls_fieldcat-seltext_s = text-c01.

ls_fieldcat-ddic_outputlen = 15.

APPEND ls_fieldcat TO gt_fieldcat.

CLEAR ls_fieldcat.

pos = pos + 1.

ls_fieldcat-col_pos = pos.

ls_fieldcat-fieldname = 'DMBTR'.

ls_fieldcat-tabname = 'GT_DISP_TABLE'.

ls_fieldcat-ref_fieldname = 'DMBTR'.

ls_fieldcat-ref_tabname = 'MSEG'.

ls_fieldcat-reptext_ddic = text-c04.

ls_fieldcat-seltext_l = text-c04.

ls_fieldcat-seltext_m = text-c04.

ls_fieldcat-seltext_s = text-c04.

ls_fieldcat-ddic_outputlen = 15.

APPEND ls_fieldcat TO gt_fieldcat.
