Unable to delete old date from Tables RSBATCH* in BW 7.3 - SAPKW73008

Hello Experts,

We have an issue in Production system - unable to delete 90 days old data from RSBATCHDATA table.

We tried exeucting report "RSBATCH_DEL_MSG_PARM_DTPTEMP" and also scheduled job using Tx. "RSBATHC" but no luck - Data is not deleted nor the job is not failing

I noticed that the field "LAST_CHK_TS" is getting stuck @ 20140611000000 and job is finishing without doing anyting

I read Note - 1942703 and reset that field to many different time stamps - earlier to the stuck value and later date to the stuck value, no matter the time stamp is jumpin to 20140611 and job is finishing.

I read all the Ntes wheni search with string "LAST_CHK_TS" but none helped.

Any idea why it it getting stuck at that date? Any idea why the data is not deleted from the tables?

Thanks,

Subbu
