Lead Time Blank Title 98954

When adding a line to a quotation there is a field Lead Time (quotedtl.leadtime). When setting up a part there is also a field called lead time under the plant tab (partplant.leadtime) Does anyone know the best way when adding a part to a quotation to populate quotedtl.leadtime with the contents of partplant.leadtime.

A detailed response would be appreciated as my knowledge is limited.

Thanks in Advance M.W.
