When we are using PP01 Transaction code by taking Object type Central Person system is showing is showing IT0001, IT0002, IT0006 and IT0009 etc. Please let us know the purpose of using all these infotypes as we have already maintained the same in PA30 u2013 Maintain master data
Could you please suggest us whether to update these infotypes here or not and what are implication of the same if we maintain them again here?
When you enter central person and click to see data it takes you to PA30 infotypes and this shows that there is CP-P relation and tells you that link exists from OM to PA for same.
It is sufficient to maintain infotypes in PA30 only as this just shows you linkage nothing more.
