Issue in Flowing Z field Value from DTR to Freight Unit

Dear All,

I am facing issue in flowing Z field value from DTR line Item to OTR. I have appended the TRQ Object and added a Z field in it. Also I have updated value in this field by using BADI /SCMTMS/TRQ_SE_REQREQ while creation of DTR.

Now I want to update the value of this Z Field in Freight Unit. For this I have appended the TOR Object and Added the Z field in It.

Now please suggest how to update the Z field value in Freight Unit by copying the value from DTR line Item? Please suggest if i need to do use some BADI for the same?

Regards,
