Active Ingredient : Correction posting after MWBQ

Question

Hello All,
We have active ingredient (purchasing scenario), now following data has been maintained :
Material master :
  a) Batch Characteristic is linked.
  b) Proportion unit has been maintained : 100 kg = 70 KAI (i.e 70% potency)
  c) Split Valuation actiavted : X
  d) Price control : V (at header level ) but price control would be 'S' for valuation type level.(Price control at material master is S)
  e) Batch management activated.
  f) Inspection type 01 linked in QM view.
  g) MWB1 done to update standard cost 1 KAI = £ 100 (this is equal to £ 70 / kg)
QM: Master Characteristic created and Material linked in the inspection plan.
Now when I raise a Purchase order  for 1 KG and price 60 per KAI and do MIGO following happens :
1. Batch is created and stock is QM restricted stock for inspection.
2. Accounting entry posted :
   Stock A/c Dr .. 70 £ (At planned potency 70%)
   GR/IR A/c Cr .. 42 £ (At PO price for planned potency 70 %)
   PPV A/c Cr ...  28 £
Then I do QA32 and put the result at 50% and do the Usage Decision, following happens :
1. Stock is moved to Unrestricted
2. Pop up comes up that ' Correct PO History for Inspection lot XXXX using MWBQ'.
This is fine so far, now I do to MWBQ and do the correction, then I see Purchase order and material document posted.
Material document is posted with movement type 141 and 142 , and accounting entry for correction is :
GR/IR A/c Dr .. 42 £
PPV A/c Cr ...  42 £
GR/IR A/c Cr ...30 £
PPV A/c Dr .... 30 £
Why is stock account not getting corrected  ?
I expected that initial entry done will be reversed completely and new stock entry would be posted. Because if I see material master for this batch ( valuation type ) it shows Total stock = 1 Value = £ 50 and Standard price updated = £ 50.
But with this in GL Stock Account in FI still has £ 70 and not £ 50 ?
Please help me understand what am I missing here .
Best Regards
Vijay

Hi Vijay,
did you actively search for accounting documents for the material or just look into the follow-on documents of the material document? It might be that the material price change was posted, but the connection to the original document is not given.
Maybe check for all accounting documents and also for a price change document (transaction CKMPCD)
