Payment Block On Vendor Invoice

[Stevens, Seth]

All,

Does anyone have any suggestions for the below scenario?  We have a
workflow used for approving and posting FI vendor invoices.  Before the
workflow posts the document we need to, possibly, set a payment block on
the invoice based on some business rules.  

We have written a call transaction to set the block; however, in most
cases the user does not have edit access so the call transaction won't
work if running under the user's ID.  We cannot set this as a background
task because there is a requirement to have advance with dialog.  I
cannot find a function module to accomplish this and obviously didn't
want to do a direct table update.

Any help or ideas would be greatly appreciated!

Thanks,
Seth
