Proc tabulate - Limit of 2147483647 potential interactions within a crossing exceeded

[EDJ]

Hello,

I'm disappointed with proc tabulate : I use it with a rather small table, dynamic number of colums selected.
As soon as 6 columns are used I get an error :

Limit of 2147483647 potential interactions within a crossing exceeded for the table statement

How does he get from 16704 observations to such a limit ????

I tried using classsdata 'cause I thought it would make it easier on the tabulate, but it doens't help.

proc tabulate data=work.DATA_EXTRACT_report_sum missing classdata=work.DATA_EXTRACT_classlevel;

class barema_PC_6_code contract_zetel_code contract_zetel_oms beheerder_nr beheerder_naam maand barema_gebruik;

var firma_aant firma_aant_barema fdcp_aant fdcp_aant_barema;

table ( (barema_PC_6_code * (contract_zetel_code * (contract_zetel_oms * (beheerder_nr * (beheerder_naam ) ) ) all='Total') ) ) ALL

, ( maand * barema_gebruik )

* ( firma_aant*SUM=' ' firma_aant_barema*SUM=' ' fdcp_aant*SUM=' ' fdcp_aant_barema*SUM=' ' );
run;

Have you taken a look at Problem Note 21125: PROC TABULATE incorrectly issues limit of potential interactions error with ODS ... ?

It may also be that the cardinality of your class variables causes the overrun.

[Kurt_Bremser]

Think of how many discrete values your class variables have.

If you have 7 variables with 20 values each, you end up with 20**7 combinations. 30 discrete values, and you are at 21 million combinations. Since TABULATE does all that in memory, there's a limit imposed on the size of the structures required.

Is there a chance your proc tabulate is specified incorrectly? Can you post a sample of your data and what output you expect?
