Hi,
Is it legal to show full stock but pay only excise for the part you moved into your manufacturing location? You should capture excise on GR and only via GR you can legally put the goods on your stocks. But if this is OK from legal point of view you might have a look at this:
You can consider 2 step GR though 103 + 105 movements. 103 is not financial movement so probably no excise would be done (GR to GR blocked stock only). You will have the goods in your stock q-ty wise but not with value. Then with 105 you will have the posting and excise captured.
Best Regards,
Tomek
