Please note - Excise implication will be applicable only when excisiable stock enters a excise reg. plant and leaves the plant.
There is no implication for within stock movement. I saw you have mentioned mvt type 201 (its wrong)
To your second point .
RG23A and C can be updated manually. This will have no impact on stock .
Only Registers will get updated against a clearing a/c.
