Sql error 901

On the weekend we loaded database ptfs group ptf# sf99102 for v4r2mo. Since 
then we getting on Sql error 901 when we run a report that has run fine 
before. I talked to ibm reported the problem, they feel if I back off 
sf52505 in 5769ss1 it might solve the problem. (best guess) . The job we 
are running starts a target ddm job from the source system to get some 
information and pass it back to the source system to create this report. 
This is day 4 & critical...the report is for distribution...the sql is 
embedded in a rpg src. Can anyone supply a work around till we solve this 
problem or back off the ptf. Thanks in advance Glenn...  
Ibm says I am the first one with this problem & this ptf sf52505 was 
created to prevent a similar problem
