BW CRM datasource for CRMD_ISU_PRAT , CRMD_ISU_CONT

Hello Experts,

I used crm datasource 0CRM_UT_QUOTATION_I to   get header and items data from CRMD_ORDERADM_H,CRMD_ORDERADM_I tables

with BJECT TYPE = BUS2000249.

Those ıtems are related with CRMD_ISU_PRAT and CRMD_ISU_CONT  tables with GUID. And I want to get related rows from CRMD_ISU_PRAT and CRMD_ISU_CONT.

Is there any standart datasource for  CRMD_ISU_PRAT and CRMD_ISU_CONT  ?

thanks.
