Summary

Content

Using the following findCustomerAccount soap call, I can successfully return data for a CustomerAccount and CustomerAccountSite, and CustomerAccountSiteUse.  However, I want the CustomerAccountSite to limit only to values where the CustomerAccountSiteUse filter criteria is true.  The current code shows multiple CustomerAccountSites, and only CustomerAcccountSiteUse sublevel for where the filter is true.  How do I filter out the non-valid CustomerAccountSite criteria?
