STO process from Plant to depot

have created an STO in which my receiving plant is a depot. I have made an outbound delivery, billing and excise invoice from the supplying plant. Now when I am doing the GR through MIGO and entering the Excise Invoice no. it is showing the excise base value as zero while the BED ECS and SECESS value are flowing correctly from the EI. The system gives an error that the excise base is zero.

Can u pls suggest what can be the issue for the same.

We are on ECC 5.0.
