Use Adobe Forms for cheque?

Hello,

we're a new implementation on ECC 6.0 and need to develop a custom check (cheque) form.

Looking at:

FBZP -> Payment method in cpny code -> Click cpny code -> expend Form Data -> Change script

We have a choice of Sapscript or PDF Form. PDF seem easier (and the new thing) - but I'd like to know if there are any gotchas concerning financial documents like cheques.

Thank you,

Jonathan
