problem with Tcode F-58 "payment advice notes"

Hi, we have the next problem, BASIS placed the monday of the past week a Service Pack "SAPKH60014" in all the clients (we have 3 dev,qas, and prd).

the next day, the tcode F-58 (Payment with Printout Header data) started printing documents without detail, The "check" is Ok, te problem is just with "payment advice notes".

When i debug the payment advice all the data is Ok, the data that doesn´t show output in printer is:

REGUP-BELNR

REGUP-XBLNR

REGUP-BLDAT

in debug each of this fields has a value, but, when it creates the document it´s created without those values.

when i browse the REGUP table, this data is saved, so it exists.

Why if the data exists in the REGUP table, in debug mode i can see those field with the right data, when printing it does´t display it in paper.

Whe tryied with the standard sapscript and with the Z sapscript and is the same.

thanks on advance,
