Regarding ABAP-HR Code

Hi Friends

I am new to ABAP-HR.I am trying to analyze below peace of code but not yet succeeded till.

So any one please illustrates me the below peace of code step-by-step.

Hi,

1) DATA: temp1 LIKE result_struc_obj.-

it declares temp1 as a internal table of result_struc_obj table that means temp1 posses all functionality, attributes of result_struc_obj.

and we are not directly make any changes to database table for that we must have create internal table.

2) In the HR ABAP, there are function modules for everything.

like in your code 'RH_GET_LEADER' FM gives manager ID of that person.

If you want to know how this function module works just go to

SE37->give function module name->display-> on the Toolbar you will see ' Function module Documentation' option.

3) IF sy-subrc = 0.

sy-subrc 0 means your Function module worked out and get output. otherwise there must be some error.

4) CLEAR- clears header line of the internal table.

REFRESH- clears contents or body of the table.

5) LOOP AT root_objects.

-

---

ENDLOOP.

it will go through each record of the table root_objects. it will help when you want to check each record of the table. we can give any conditon after loop at. on that basis loop will execute.

6) READ TABLE -

---

it reads one record of the table at a time.

7) MOVE-CORRESPONDING - it will move all record to respective fields.

reward if useful.
