Position ID is not display in IT1(OM and PA intergartion)

Dear Expert,

We had change cost center in position id though PO13(Position) and it should be reflected new cost center in infotype 0001. but it does not reflect.

so we run RHINTE30 and wants to check OM data is transfer into PA.

But when we check Infotype 0001, we found that system had took default position i.e.99999999 instead of original position ID.

now we want to bring back are original position id in IT1.

So please help us to rectify the error.

Thanks
