IE error after ITS patch update.

Hi all,

We recently patched our ITS 6.20 to SPS 22. We have our ESS iViews in EP6 SPS 17 being rendered by the ITS. For our Pay Statement we have a table in the top iView and an adobe iView underneath it. Every time the pay statement iView is loaded we see the IE6 error popup "Transaction PDF is unknown". Even though the PDF is displayed fine in the lower iView. Does anyone have an idea to why this is happening? Our version of R/3 is 4.6c
