We have tried to increase the initial and maximum heap size in the Agentry.ini file from 256 / 512 to 512 / 2048 respectively. But the
error still persists.
Can you please let us know if there are any
other changes required for
the same?
PFA the Java backend and the user
logs. Please treat this ticket with
the highest priority.
Thanks,

Looks like ur getting   heap size error while trying to fetch  records for ctparts complex table. From platform  point of view you have increased heap size. Next step is to analyze application settings for ctparts  complex table. As indicated by Steve from application point you need check the need for  amount of materials your trying to retrive , can you set filter for ctparts ,  does  ctparts  BAPI execute in SAP without any timeout error.
What is the version of Work Manager your using ?    With WM 6.1 you have options to  take advantage of data staging that is delievered as part of standard application.
