Batch specific unit of measure - Purchase order history correction

Question

I have maintained an alternate proportional unit for a material.  This alternate unit is used as the order price unit in the purchase order.  I have created a batch characteristic which is linked to this proportional unit of measure. I have also created a Master inspection characteristic which is linked to this batch characteristic.
I want to correct the purchase order history using quality management by transaction code MWBQ.  However, when I perform transaction MWBQ, the inventory is reduced to zero and entire amount is posted to price difference account after correction. Hence, my inventory value becomes zero after MWBQ. I cannot maintain the proportional unit at standard price since this is a raw material.  Need a solution on how to post correction in purchase order history without actualy making the inventory zero and with moving average price.

Answer 1

Thanks for caring!
As for transaction MMBE it all looks fine. So basic definitions must be OK up to that point.
I think the point is to set requirement for the amount of active ingredient.
Do the batch determination for this.
Do the goods issue in physcial quantity which is the base unit of measure.
I did try now with KG in the BOM. I still get  double items in the process order. Now both in KG.
One line is correclty copied.
The incorrect line which is the same in both cases says 1 KG. which is the correct conversion from  0,01KAI.
