Hi Juan,
So now u have the org unit ID.
Use the same FM RH_STRUC_GET now to get all the position IDs which are belongs to that org unit.
Pass act_otype = 'O',act_objid = ourg unit ID that u have,act_wegid = 'B003' and in the result_tab u will get all the positions under this org unit.
Now u use the same FM to get the pernr which holds these positions.
Loop in the result tab."as u need to get pernr for all those positions
Use the FM RH_READ_OBJECT to get the position validity begin date and validity end date.
Pas the values in the same order as above 'S',result_tab-objid,'A008' and in the result tab u will get pernrs.
Now use the FM HR_READ_INFOTYPE to get first name for IT0002-VORNA by providing the pernr.
Now use the FM HR_READ_SUBTYPE to get user ID from IT0105 subtype 0001 field USRID by providing the pernr.
Populate all these data to final itab.
Endloop.
Thanks
