Determine the immediate child WBS element of a WBS element

Question

Hi,
I would like to know how to determine on how to know all the immediate childs of 1 parent (example: how can i kno all level 3 elements under level 2 b?)  The usage of PRPS-STUFE is not enough since it only indicates levels.  I also noticed we do not have entries in PRHIS table, is it because of we are not using the standard WBS?
Level 1
     Level 2 a
     Level 2 b
          Level 3 a (of level 2 b)
          Level 3 a (of level 2 b)
     Level 2 c
          Level 3 a (of level 2 c)
Thanks!

Hi,
The project hierarchy is data is available in PRHI table.
PRHI'S' is for standard structures. S stands for standard.
PRHI is for operative structure.
If you want to know the WBSE immediately under a WBSE say A. Then go to PRHI table enter A in POSNR field. The WBSE under it will be available in PRHI-DOWN field.
If u have more than one WBSEs under A and you are looking to get all of them. Then u may have to rite a Z function module. Logic can be as under.
Assume WBS structure is as below
Level 1 = A
Level 2 = B,C,D.
When u give A as input u want BCD as output.
Then
Take input as 'A'.
1) Go to PRHI and enter A in POSNR. Collect PRHI-DOWN and Store.
2) Again go to PRHI and enter PRHI-DOWN (collected above) in POSNR. Collect PRHI-RIGHT and Store.
3) Again go to PRHI and enter PRHI-RIGHT (Collected above) in POSNR. Colect PRHI-RIGHT and Store.
4) Repeat step 3. untill PRHI-RIGHT = Initial or Zero.
This Function module will give u all the WBSEs assigned in immediate one level less than the input WBSE.
Please post ur findings after u try this.
