Job (settlement of CO orders) RKO7CO88 stopped - protocoll full

Hi,

during RKO7CO88 (settlement of CO orders) I get the message BL252 "message number 999999 reached". The log is full.

I learnt from SAP OSS etc. that it may be due to the wide selection we use.

How can I reset the message numbers or delete them?

Thanks a lot for any input.

Thomas
