Simplistically, split your decision table into smaller ones.

To answer your question more fully; the maximum number of rows that can exist in a XLS is (IIRC) 65535.

That said; how many can be processed on a given computer, depends on how much RAM has been associated with the JVM heap and how many decision table columns are on a row.

With kind regards,

Mike

What is the maximum number of rows you can use in a decision table? I need
to use over 12,000 rows but seem to get an out of memory error for even
1,000 rows. I already increased the memory used.
What are my options if I need to lookup values for that many rows?
