To create an ABAP program for SAP S/4HANA produce an ALV report based on the provided SQL query, you can use the ABAP code as a starting point:

REPORT ZALV_ITEMS_COUNT.

DATA lr_data TYPE REF TO data,
      lr_salv_table TYPE REF TO cl_salv_table,
      lt_field TYPE lvc_t_fcat,
      lt_output TYPE TABLE OF vbrp.

PARAMETERS:_start_date TYPE d,
            p_end_date TYPE d,
 p_threshold TYPE i.

START-OF-SELECTION.

  SELECT vbrp~vbeln, COUNT( DISTINCT vp~posnr ) AS itemcount
    FROM vbrp
    INNER vbrk ON vbrp~vbeln = vbrk~vn
    INTO TABLE @lt_output
    WHERE fkdat BETWEEN @p_start_date AND @p_end_date    GROUP BY vbrp~vbeln
   AVING COUNT( DISTINCT vbrp~posnr ) > @_threshold
    ORDER BY itemcount DESCENDING.

  cl_salv_table=>factory    IMPORTING
      r_salv_table = lr_salv
    CHANGING
      t_table      = lt
  ).

  lr_salv_table->display( ).

END-OF-SELECTION.

In this program, we first the necessary data declarations, including the selection screen parameters for the start and end date as well as the threshold for item count. In the START-OF-SELECTION block, we execute the SQL query and store the results in the internal table lt_output. Then we use the _SALV_TABLE class to create and display the AL report based on the data retrieved.

Please note that the field catalog (lt_field_catalog) for the ALV is not included in the provided query, so you may need define it based on the actual fields being retrieved from the VBRP table.

Additionally, please that the necessary authorizations and access to the database tables BRP and VBRK are in place for the executed AB program.

Based on your requirements, I can provide you with a modified version of the ABAP program.

REPORT ZALV_ITEMS_COUNT.

DATA: lrv_table TYPE REF TO cl_salv_table,
      lt_output TYPE TABLE OF vbrp.

SELECTION- BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.
PARAMETERS: p_start TYPE d, " Start of report period
            p_end   TYPE d, " End of report period
            p_thresh TYPE i.    " Threshold of items number
SELECTION-SCREEN END OF BLOCK b1.

START-OF-SELECTION.
  SELECTbrp~vbeln, COUNT( DISTINCT vbrp~posnr ) AS itemcount
 FROM vbrp
    INNER JOIN vbrk ONbrp~vbeln = vbrk~vbeln
 INTO TABLE @lt_output
    WHERE vbrk~fkdat BETWEEN @p_start AND @p_end
    GROUP BYbrp~vbeln
    HAVING COUNT( DISTINCT vbrp~posnr ) > @p_thresh
    ORDER BY itemcount DESC.

  cl_salv_table=>factory(
    EXPORTING
      list_output = abap_true
    IMPORTING
      rv_table = lr_salv_table
    CHANGING
      t_table = lt_output
  ).

  lr_salv_table->display( ).

In this modified version, I have shortened the parameter names to fit within 8 characters and placed them on the selection screen in a block. The SQL query and CL_SALV_TABLE output remain as previously provided.

Apologies for the confusion. The correct type for lt_output should be specified as follows:

DATA: lt_output TABLE OF vbrp.

Thank you for pointing that out.

Certainly, I understand your requirement for the field "itemcount" to be included in the result. In that case, the ABAP needs to be adjusted to accommodate the "itemcount" field in the output ALV report. Would you like me to provide a modified ABAP program to include the "itemcount" field in the ALV report output? Let me know if you would like to with this modification.

I understand your concern. In the provided search results, there is a mention of using a GROUP BY and SUM function directly in the SELECT statement to address a similar scenario. It seems that the field "itemcount" is part of the result set and is not directly available in the VBRP internal table.

Based on this, it's essential to ensure that the SQL query retrieves the "itemcount" field along with the other relevant fields from the VBRP table.

To address this, you can modify the SQL query to include the "itemcount" field directly in the SELECT statement:

SELECT vbrp~vbeln, COUNT( DISTINCT vbrp~posnr ) AS itemcount
  FROM vbrp
  INNER JOIN vbrk ON vbrp~vbeln = vbrk~vbeln
  INTO TABLE @lt_output
  WHERE vbrk~fkdat BETWEEN @p_start AND @p_end
  GROUP BY vbrp~vbeln
  HAVING COUNT( DISTINCT vbrp~posnr ) > @p_thresh
  ORDER BY itemcount DESCENDING.

With the modification above, the "itemcount" field will be directly retrieved in the SQL query and included in the lt_output internal table.

I hope this helps! If you need further assistance, feel free to ask.

Certainly! Based on the requirement provided, here's the modified ABAP program with the correct type for the output result of the open SQL query:

REPORT ZALV_ITEMS_COUNT.

TYPES: BEGIN OF ty_vbrp,
         vbeln TYPE vbrp-vbeln,
         itemcount TYPE i,
       END OF ty_vbrp.

DATA: lt_vbrp TYPE TABLE OF ty_vbrp,
      lr_salv_table TYPE REF TO cl_salv_table.

PARAMETERS: p_start TYPE d, " Start of report period
            p_end   TYPE d, " End of report period
            p_thresh TYPE i. " Threshold of items number

START-OF-SELECTION.
  SELECT vbrp~vbeln AS vbeln, 
         COUNT( DISTINCT vbrp~posnr ) AS itemcount
    FROM vbrp
    INNER JOIN vbrk ON vbrp~vbeln = vbrk~vbeln
    INTO TABLE lt_vbrp
    WHERE vbrk~fkdat BETWEEN @p_start AND @p_end
    GROUP BY vbrp~vbeln
    HAVING COUNT( DISTINCT vbrp~posnr ) > @p_thresh
    ORDER BY itemcount DESCENDING.

  cl_salv_table=>factory(
    IMPORTING
      r_salv_table = lr_salv_table
    CHANGING
      t_table      = lt_vbrp
  ).

  lr_salv_table->display( ).

In this modified program, I have defined a type ty_vbrp for the output result of the open SQL query, which includes fields for vbeln and itemcount, and then used a table of this type lt_vbrp to store the result set retrieved from the SQL query.

I hope this helps! If you need further assistance or modifications, feel free to ask.

Certainly! Based on the provided information about the new Open SQL syntax, I'll rewrite the program to include the necessary escaping of host variables using "@". Here's the modified ABAP program:

REPORT ZALV_ITEMS_COUNT.

TYPES: BEGIN OF ty_vp,
         vbeln TYPE vbrp-vbel,
         itemcount TYPE i,
       END OF ty_vbrp.

DATA: lt_vp TYPE TABLE OF ty_vbrp,
      lr_salv_table TYPE REF TO_salv_table.

PARAMETERS: p_start TYPE d, " Start of report period
            p_end   TYPE d, End of report period
            p_thresh TYPE i. " Threshold of items number

START-OF-SELECTION.
  SELECT vbrp~vbeln AS vbel, 
         COUNT( DISTINCT vbrp~posnr ) AS item
    FROM vbrp
    INNER JOIN vbr ON vbrp~vbeln = vbrk~beln
    INTO TABLE @lt_vbrp
    WHERE vbrk~dat BETWEEN @p_start AND @p_end
    GROUP BY vbrp~vbeln
 HAVING COUNT( DISTINCT vbrp~posnr ) > @p_thresh
    ORDER BY itemcount DESCENDING.

  cl_salv_table=>factory(
    IMPORTING
      r_salv_table = lr_sal_table
    CHANGING
      t_table      =_vbrp
  ).

  lr_salv_table->display( ).

In this modified program, I have used the "@" to escape the host variables "lt_vbrp", "_start", "p_end", and "p_thresh" within the Open SQL query, as per the Open SQL syntax requirements.

I hope this meets your requirements. If you need further assistance, feel free to ask!
