3793083 - Error "Rule Set too Large/Complex to compute" During determine service levels activation

• Rule set too large/complex to compute. Please reduce/simplify rule set and try again.
• The error occurs when activating the Determine Service Levels rule set (SLA determination).
• Backend short dump code observed during activation: GEN_TOO_MANY_CBS.
• In some tests, a validation message "Value exceeds maximum length 4" was seen.

1. Open the SLA determination (Determine Service Levels) rule set.
2. Upload or maintain the decision table with the intended rules.
3. Start activation of the rule set.
4. Observe the error "Rule set too large/complex to compute. Please reduce/simplify rule set and try again."

• During activation, the generated backend program exceeds ABAP runtime limits, producing dump GEN_TOO_MANY_CBS: "You attempted to create more than 15,000 control blocks of type DATA."
• The decision table contains a very large number of rule entries (e.g., >10,000), causing excessive generated code volume; activation then fails and surfaces the error "Rule set too large/complex to compute."

1. Review the Service Level determination decision table and reduce the overall number of maintained rule entries (for example, remove redundant lines, consolidate conditions, or simplify combinations) to lower the generated code volume.
2. Revalidate the file to ensure consistent and valid data in all sheets and columns, then upload and activate again.
3. If the issue persists, refer to the guidance in the referenced notes for optimization strategies and known framework limitations.

• Refer to: 3267010 - Rules cannot be uploaded, error: "Rule set too large/complex to compute | Please reduce/simplify rule set and try again"
• Refer to: 2893833 - Error message "Rule set too large/complex to compute" is shown even for simple rules
• Refer to: 3637417 - Error: "Rule set too large/complex to compute"
