Hello Rose,
Gopi already provided information, I just wanted to add few things in addition.
Program - COM_PRODUCT_DELETE_ALL - to delete all product masters from AII
Program - COM_PRODUCT_DELETE_SINGLE - to delete single product master from AII
Before running this program you have to add entry in table COMC_PR_TOOL_REG, for program name, user ID & date. Without these entry it will not allow you to execute above programs.
Hope this helps.
Thanks,
NRS
