Use/Impact of ATO/PTO in PH4C to External Systems.
For creating the structure and trying to associate parent-child relationship. The BOM Item Type for the parent is Model and Child BOM Item Type Can be Standard/Option Class.
Parent BOM Item Type = Model
Child BOM Item Type = Standard/Option Class
Then I tried to associate it gives error as" to populate the Item ATO/PTO Values" then I have given ATO=Yes Then I was able to proceed with my work.
When I give Parent BOM Item Type = Model and ATO=Yes then for the child BOM Item Type = Standard/ Option Class and ATO = Yes Then I was able to proceed with structure with no issues.
