I think I have found the problem but I don't know how or even if I can fix it.  The field BKAR.INV.TERMD has a field length of only 10.

It isn't just SO-A that shortens it, it's any form that uses  BKAR.INV.TERMD  as the data in the terms field. This field has a set length of 10 as opposed to the terms table field length of 20.  We need those other 10 characters to show on our forms.   I don't see how to use the terms table on the forms editor since that table is not opened by the (sales) forms in question. ( See a different discussion on the forms editor under Evo/ERp I think)
Can anyone help me?  We have two terms that are similar except for the last characters, XX% Dep, Net 30 and XX% Dep, Net PPD.  When these print, they look the same!
