Dump when using Decision Table with around 10,000 entries

Hello Experts,

We are getting a dump(GEN_TOO_MANY_CBS) while using a decision table(2 Columns) that contain more than 10,000 entries(In Generation mode). If we use 'Interpreation' mode, the performance is very bad. Could you please clarify

1. Is there any recommendation/restriction to the number of entries in a decision table?
2. Is there any way to improve the performance OR to get rid of this dump.

Please advice. Thank you.

Regards,

Gupta
