The AFIH Table - Maintenance order header - tends to be a large table for many companies. It could be that the system is simply overloaded while caching all of this data in RAM.

One way to reduce the amount of memory needed is to select the desired output fields; it may not be necessary to extract the free-text fields like DEVICEID (40 bytes), ADPSP (40 bytes) or UII (72 bytes).

Additionally, it may help to define a where clause and filter the data by date, plant or work center.
