How to write ABAP HR reports in ABAP web dynapro

Hi All,
How to write ABAP HR reports in ABAP web dynapro? We can add HR REPORT CATEGORY in ABAP HR using logical database like PNP.How to add HR REPORT CATEGORY in ABAP Webdynapro ?
Thanks.

You can't use legacy concepts like logical databases directly in Web Dynpro ABAP. Even if you could do so, you shouldn't. Web Dynpro ABAP should always follow MVC - meaning that your business logic (the model) should be separated from WD as much as possible. This means calling function modules or class methods to consume the business logic and data. So in general there should be no difference between building HR reports or any other type of report in WDA - since from the WDA side you are calling other objects to consume the data.
This probably does mean that you will need to create classes to expose the HR data that you want in your WDA.

How to write macro's in hr abap

Hi,
All
I am new to HR ABAP .Does any body give links to write macro's in HR ABAP
Thanks in advance.
regards
Ram

h,
adding to the aboce post.
chk this.
Macros:
Introduction
Programs that process the cluster data (for example, RX) do not access the cluster independently. The data is accessed using a defined interface created with macros.
Macro contains some part of source code which it will be useful for number of applications. Macro is module which is stored
Naming Conventions of Macro:
RP-aaa-bb-cc
     aaa is the type of Macro. It takes two values
o     IMP Import Macro
o     EXP Export Macro
     bb is the Database table where the data is saved:
o     C1 Database object PCL1
o     C2 Database object PCL2
o     C3 Database object PCL3
o     C4 Database object PCL4
     Cc is the cluster, it may take
o     RX Cluster object RX
o     RD Cluster object RD
o     B2 Cluster object B2      and so on.
Defining and Calling the Macros
Defining:
There are two options for defining the Macros
     Macros are defined using the ABAP Commands DEFINE.END-OF-DEFINITION. A macro can be used within a report or within include. If a macro is used in a report, and the macro is defined in include with the DEFINE command, include must be integrated.
     Macros can also be defined as RMAC macros. The source code of these modules is stored in the function section of the control table TRMAC. The coding is grouped under a specific name in the table key.
According to conventions, the first two letters of the name must stand for the application. The rest of the name is freely definable.
Difference between the two methods is:
     If a macro is changed, each report using this macro is automatically regenerated when it is executed.
     When you change a RMAC macro in the table TRMAC, the reports that use this macro are not regenerated automatically. You must regenerate them manually.
Standard HR Macros
o     The macro RP-PROVIDE-FROM-FRST retrieves the first(start) data record which is valid in the data selection period.
o     The macro RP-PROVIDE-FROM-LAST retrieves the last(latest) data record which is valid in the data selection period.
o     The macro RP-READ-INFOTYPE retrieves the data record(s) which is valid in the data selection period.
How to check whether the macro operation is successful or not
For every macro, whether the operation was successful or not will be checked with
PNP-SW-FOUND.
If PNP-SW-FOUND = 1, then the operation is successful.
Where exactly the Macro code is stored
The program code pertaining to this macro is stored in the control table RMAC
Guidelines for how and when to use the Standard Macros
o     RP_PROVIDE_FROM_FRST
Use macro RP_PROVIDE_FROM_FRST in programs for the logical databases PNP and PAP where the first data record for a period (can be a subtype) is read from an infotype table. The infotype table has been filled earlier (for example, with GET PERNR or RP_READ_INFOTYPE). This macro is only helpful if the infotype has time constraint 1 or 2.
Prerequisites
     The validity begin date of the time period must be before or the same as the validity end date.
     Validity start and end dates are correct (preferably of the type DATE).
     The infotype table is sorted in ascending order. Otherwise, you would receive the first fitting table entry that might not necessarily correspond to the first time entry.
Features
The first entry for a specified period is placed in the table header entry from an internal infotype table.
Parameters
RP_PROVIDE_FROM_FRST inftytab subty beg end
IN :     1)     Name of the internal table
     2)     Subtype required or SPACE if no subtype is being specified
     3)     Validity start date of the time interval
     4)     Validity end date of the time interval
OUT:     1)     PNP-SW-FOUND: has the value 0 if there is no matching entry in the infotype table in the given time period. Otherwise it has the value 1.
     2)     The matching table header entry if PNP-SW-FOUND = 1 or
the initial table header entry if PNP-SW-FOUND = 0
Example
(RP_PROVIDE_FROM_FRST inftytab subty beg end)
RP_PROVIDE_FROM_FIRST P0021 '1' PN-BEGDA PN-ENDDA.
IF PNP-SW-FOUND EQ '1'.
ENDIF.
or
RP_PROVIDE_FROM_FRST P0001 SPACE PN-BEGDA PN-ENDDA.
IF PNP-SW-FOUND EQ '0'.
WRITE: / 'Error: Org. assignment is missing' REJECT.
ENDIF.
o     RP_PROVIDE_FROM_LAST
You use macro RP_PROVIDE_FROM_LAST in programs for the logical databases PNP and PAP where the last data record for a period (can be a subtype) is read from an infotype table. The infotype table has been filled earlier (for example, with GET PERNR or RP_READ_INFOTYPE). This macro is only helpful if the infotype (or subtype) has time constraint 1 or 2.
Prerequisites
     The validity begin date of the time period must be before or the same as the validity end date.
     Validity start and end dates are correct (preferably of the type DATE).
     The infotype table is sorted in ascending order. Otherwise, you would receive the last fitting table entry that might not necessarily correspond to the last time entry.
Features
The macro RP_PROVIDE_FROM_LAST makes sure that the last entry for a specified period is placed in the table header entry of the report output list.
Parameters
RP_PROVIDE_FROM_LAST inftytab subty beg end
IN :     1) Name of the internal table
     2) Subtype required or SPACE if no subtype is being specified
     3) Validity begin date of the time interval
     4) Validity end date of the time interval
OUT:     1) PNP-SW-FOUND: has the value 0 if there is no matching entry in the infotype table in the given time period. Otherwise it has the value 1.
     2) The matching table header entry if PNP-SW-FOUND = 1 or
the cleared table header entry if PNP-SW-FOUND = 0
Example:
RP_PROVIDE_FROM_LAST P0021 '1' PN-BEGDA PN-ENDDA.
IF PNP-SW-FOUND EQ '1'.
ENDIF.
OR
RP_PROVIDE_FROM_LAST P0001 SPACE PN-BEGDA PN-ENDDA.
IF PNP-SW-FOUND EQ '0'.
WRITE: / 'Error: Org. assignment is missing'. REJECT.
ENDIF.
     RP_READ_INFOTYPE
You can use the macro in all programs at any point. You can also use it in function modules. In database PNP, an infotype is usually read with GET PERNR. Using macro RP_READ_INFOTYPE is an exception.
You can also use the function module HR_READ_INFOTYPE. For information on how to use the function module, see the documentation on Function Modules.
Prerequisites
     The validity begin date of the time period must be before or the same as the validity end date.
     Validity begin and end are correct date specifications (preferably of the type DATE).
     The infotype table must match the infotype number.
     The program using the macro must contain the include DBPNPMAC.
Features
The macro RP_READ_INFOTYPE makes sure that all data records for a person for the specified period are placed in an internal infotype table.
Parameters
RP_READ_INFOTYPE pernr infty inftytab beg end
IN :     1)     Personnel number of the person requested
     2)     Infotype number of the required infotype
     3)     Name of the internal infotype table
     4)     Validity start date of the time interval
     5)     Validity end date of the time interval
OUT:     1)     PNP-SW-FOUND = 0, if there is no matching record in the dataset
           PNP-SW-FOUND = 1, if there is no matching record in the dataset
     2)     PNP-SW-AUTH-SKIPPED-RECORD = 0, if the HR authorization check has not retained any records due to incorrect authorizations.
           PNP-SW-AUTH-SKIPPED-RECORD = 1 , if the HR authorization check has retained at least one record due to lack of authorization
     3)     Internal infotype table, containing all matching records for which the user is authorized (this table can also be empty).
Example
(RP_READ_INFOTYPE pernr infty inftytab beg end)
   INFOTYPES: 0001.
   RP-LOWDATE-HIGHDATE.
DATA: PERNR LIKE P0001-PERNR.
DATA: BEGDA LIKE P0001-BEGDA, ENDDA LIKE P0001-ENDDA.
PERNR = '12345678'.
BEGDA = LOW-DATE + 15
ENDDA = HIGH-DATE - 5.
RP-READ-INFOTYPE PERNR 0001 P0001 BEGDA ENDDA.
IF PNP-SW-AUT-SKIPPED-RECORD EQ '1'.
WRITE: / 'Insufficient authorization'. STOP.
ENDIF.
IF PNP-SW-FOUND EQ '0'.
WRITE: / 'Infotype 0001 missing'. STOP.
ENDIF.

How to write select within select in ABAP

Hi Guys
I want to write a select statement in ABAP to select from 2 tables below is my code I want to write select within select statment in --->A and replace with ---> B
FORM sales_production_order USING    p_vbeln TYPE vbeln_va
                             CHANGING p_aufnr TYPE aufnr
                                      p_rtcod TYPE sysubrc.
CLEAR: p_rtcod,
         p_aufnr.
A *******
SELECT aufnr FROM aufk INTO p_aufnr UP TO 1 ROWS
    WHERE kdauf EQ p_vbeln .
B *******
SELECT kdauf from aufk into p_aufnr UP TO 1 ROWS
    WHERE KDAUF IN ( SELECT VBELN FROM VBAP where vbeln EQ p_vbeln) .
ENDSELECT.
p_rtcod = sy-subrc.
ENDFORM.                    " sales
T

Hi Eslam,
In select statements, ENDSELECT must be added when single line returned without the addition 'SINGLE'.
The innner query in your code, returns a single record but with the addition 'UP TO 1 ROWS'. The outer query also like this only. But the outer query ended with 'ENDSELECT', not for inner query.
Else you can add 'SINGLE' keyword.
SELECT aufnr FROM aufk INTO p_aufnr UP TO 1 ROWS
    WHERE kdauf EQ '10' .
    SELECT SINGLE kdauf from aufk into p_aufnr
    WHERE KDAUF IN ( SELECT VBELN FROM VBAP where vbeln EQ p_vbeln) .
ENDSELECT.
SELECT aufnr FROM aufk INTO p_aufnr UP TO 1 ROWS
    WHERE kdauf EQ '10' .
***** It assigns Nth record's KDAUF to p_aufnr provided N records satisfy the condition.
    SELECT kdauf from aufk into p_aufnr UPTO 1 ROWS
    WHERE KDAUF IN ( SELECT VBELN FROM VBAP where vbeln EQ 'p_vbeln) .
    ENDSELECT.
ENDSELECT.

Hi Jyotirmoy,
Check this thread for Subquery
http://help.sap.com/saphelp_nw04/helpdata/en/dc/dc7614099b11d295320000e8353423/content.htm
Correlated, non-scalar subquery:
REPORT demo_select_subquery_1.
DATA: name_tab TYPE TABLE OF scarr-carrname,
      name LIKE LINE OF name_tab.
SELECT carrname
INTO TABLE name_tab
FROM scarr
WHERE EXISTS ( select *
                   FROM spfli
                   WHERE carrid   = scarr~carrid AND
                         cityfrom = 'NEW YORK'        ).
LOOP AT name_tab INTO name.
WRITE: / name.
ENDLOOP.
This example selects all lines from database table SCARR for airlines that fly from New York.
Scalar subquery:
REPORT demo_select_subquery_2.
DATA: carr_id TYPE spfli-carrid VALUE 'LH',
      conn_id TYPE spfli-connid VALUE '0400'.
DATA: city TYPE sgeocity-city,

SELECT SINGLE city latitude longitude
INTO (city, lati, longi)
FROM sgeocity
WHERE city IN ( select cityfrom
                    FROM spfli
                    WHERE carrid = carr_id AND
                          connid = conn_id      ).

This example reads the latitude and longitude of the departure city of flight LH 402 from database table SGEOCITY.

How do we track back the ABAP queries/report painter used to custom report?

Hi Experts,
I only have some ideas about report painter and ABAP query. If a company has a number of different Z reports in production.
1. How do we identify if it's report painter/writer or ABAP query??
2. For ABAP query report, suppose that i can identify one. If i am given a Z tcode of that report and identify the program of that report behind it, How do i know what query that program belongs to?? What are the steps i go back in SQ03 to view that query??
3. For report painter, starting from ztcode of the report, where do i check and track the original painter of that report??
Please help clarify my doubts..
Monica

Hi Monica,
For report painter/writer, you can identified it by go to
Environment --> Technical information when you execute your Z-tcode.
To refer back to the report painter/writer t-code you just need to double click oh the report group that you see by clicking the link above.
Thanks,
Victor.
