Adding New Transaction on P0018

Dear All,

We are trying to add one new transaction on P0018(Standard Application) Tax Revisions File and getting error of "Not found in user Defined Code"(error Code 018A - coming from Grid column Order Type(DCTO) - 00/DT)

This is happening in JDE 9.1. System is checking for Order Type in detail line for hidden column(DCTO) and since Blank is not defined in UDC 00/DT, system is displaying error.

In Xe for the same scenario, system is allowing to add new transaction.

If we create new line by copying the existing line, We do not have this issue in 9.1.
