KKFN vs KKF6M Error

Dear CO Experts,

When running transaction to create product cost collector, i encountered an issue regarding KKF6M tcode, wheni try to execute this tcode for certains material, there is error that 0 Product Cost Collector created, but strangely when i execute the material one by one via tcode KKF6N, no issue arose and the product cost collector created. Is there any missing configuration i miss? or anything else? i am working for SAP S/4 Hana

Regards,

Angga
