Hi,
Check in J1ID vendor excise details. There against the vendor, you have to put excise indicator as "1", along with other details.
After maintaining this, test the scenario.
If excise details and value are not getting defaulted in migo, please check chapter ID, material-chapter id combination, and excise tax rate.
After that check the configuration for excise defauklts in SPRO-Logistic Gen - Tax on Goods movement - India - Basic Settings - Determination of excise duty - maintain excise defaults. This is the main cionfiguration setting, that brings the excise values defaultly in migo.
Also, check the settings - classify condition types and assign the tax code to companty code.
Hope its helpful.
Regards,
