Timestamp data difference between RSA3 and PSA

Hi,

I have some Timestamp fields in datasource i.e. Created_TS, Changed_TS, DueDate_TS....etc. They are SAP standard fields.

Out of all these Timestamp fields, data for Creation_TS and Changed_TS don't reconcile in RSA3 and PSA. Data for DueDate_TS is fine.

example Created_TS:

in RSA3: 07.07.2014 12:59:48

in PSA: 20140707105948

example Changed_TS:

in RSA3: 09.07.2014 18:37:13

in PSA: 20140709163713

I have checked in source system and both Created_TS and Changed_TS are using domain: COM_TSTMP which has a converison routine TSTLC.

while Duedate_TS is using conversion routine TSTPS.

how can get correct data in PSA?

Thanks

Ahmed
