How to commit rules in territory management in sap crm using custom code ?

Hi Experts,

Please suggest some solution about how to commit rules in territory management in sap crm using custom code ?

I have created a report in which i am creating territory using custom code n now i have to assign rules to the territory.

i have a flat file which contains territory id, accounts, ruleset id.

i have uploaded this flat file using my report now my program is able to create territory n rule guid.

I am using PERFORM commit_rollback IN PROGRAM crm_terrman_data_migration to commit the rules.

Now the issue is that it is commiting only the rule only for the first record n not for the rest of the records.

Please suggest some solution.

TIA
