Hello Satish,
First did you try to enter excise invoice manually for movement type 673?
If it allows you to post there, then it might be some problem with field mapping for automated excise invoice capture.
Or you can try to got to following places
1. OMJJ -- Settings for movement type 673
2. IMG --> Material Management -->Inventory Management and Physical Inventory -->Excise Duty (all settings in here)
Let me know if it works or not.
Thank you.
