History in CDPOS

Hi all,

I am facing a problem :

I want to know, for a special VBAP (left say, p_vbeln – p_posnr) what was the last value of its material (MATNR)

I say ‘last value' because VBAP-MATNR can be changed.

When VBAP has not been deleted

     I can read VBAP and the answer is VBAP-MATNR.

If the material has been changed at least once BUT VBAP has been deleted.

I have to select CDPOS with

        Tabkey = “p_vbeln p_posnr”  /   CHGNID = ‘U’   /   FNAME = ‘MATNR’

            Then sort CDPOS by CHANGENR

            Get the last CDPOS

            My answer is CDPOS-VALUE_NEW

If the material has never been changed and if VBAP is deleted : I'm stuck ! 

• Is there a way to retrieve the MATNR that had been put on this VBAP ?
• Is there a way to log, in CDPOS, the value of MATNR when VBAP is deleted ?
  (And not only FNAME = 'VBAP' - CHNGID = 'D' VALUE_NEW = '' VALUE_OLD= '' which is really useless...)

 

Thanks for any idea….
