AUDAT field missing in Standard DataSource 2lis_11_Vaitm

Hi,

All the Sales Standard Extractors(2LIS_11_VAITM, HDR,SCL ect.) do not have AUDAT Field.I have got AEDAT, ERDAT etc.

What could be the reason? My Support Paare up to the Highest level(SAPKW70022).

Has anyone faced similar situation?

Regards,

Samir
