How to load info type 7410 career types to Jobs or Positions

Hello Expert,

I’m trying to use T-code PP01 to load career types and career levels (info type 7410 ) by LSMW,

But I’m not able to maintain info type 7410 by pp01,

I had change the table T77CD to accept maintain infotype from standard transaction,

But getting below error:

“Time constraint not found for S 7410”

Any advice please on how to load career types and levels by LSMW

Thanks
