Hi Shyam,
What is your Price indicator for semi finished good?
If it is S-Standard Price. Everytime GR is done Posting will be made based on Standard Price updated in Material master(thro Product Costing CK11n & CK24). So what is purpose of using batch based Split valuation if Invenotry(MAterial+Valuation type) is valued at same Price.
Assume that you are using Moving avg Price for Semi-finished Goods
If it is V-Moving avg Price -SAP already reconizes that there would be huge difference in valuation in production order , because of timing difference of Goods issue later than Goods receipt. This is already recomended to 'Not ' Use.
Batch based split valuation is for Purchased part... It should not be used for Manufactured parts/Semi finished goods.
It just provides addtional valuation , if Different purchased order has different price.
There is no value in activating this functionality even for procured parts, if you are not going to use this information further on where each of these differently valuated batch are used.
First ,identify what business requirement you are trying to address.
Best R,
Jatin
