Data load issue with generic data source

Hi Experts,

We are facing issue at BI end that data is not loading properly from ECC. Lot of records got missed out. So we planned to delete entire content and reload the data.

We have generic data source GECCTD_INBOUND_DEL_DATA loading through function module.

Here timestamp got updated in table ROOSGENDLM as you aware.

My doubt is, how to reset the timestamp in this table so that we can load the data, because even I delete the content at BI, timestamp is not changing.

Do I need to edit manually here or is there any other way to complete this action.

Thanks,

Saravanan
