Data extract to BI (extractor 0AU_PPC_CONF_1) - PPC_HEAD, PPC_ORD_INF

Hi experts,

I tried to extract data from R/3 via extrator 0AU_PPC_CONF_1 into a BI system in delta mode.

This extractor gets data from tables

PPC_HEAD (Document PP Backflush - Header)

PPC_ORD_INF (Information on APO Order)

But now I cannot restart the data load initialization because the table PPC_HEAD has 2 BW-markers and these markers are filled with ‘X’.

FLG_BW_GI (Transfer goods issues to BW)

FLG_BW_CONF (Transfer backflushes to BW)

Can anyone tell me how I can delete these markers (transactioncode? spro?,,,) in the table (official way) and so I can restart a complete transfer to BW?

Thanks a lot.

Raimund
