Problem with new Stat sub transaction

Hi Team,

i have created a new Stat miscellaneous debit sub-transaction and completed all settings including FQZB. and i have posted the manual transaction through FPE1.

actually as per our process if there is any stat open item it will adjusted in current bill by doing account clearing automatically and it will show in Bill form.

but for this new stat sub transaction is not showing in bill and not happening account clearing also. please advise how to find out the problem.

note: i have checked with existing main/sub and posted the manual posting and generate the bill. for those transactions are performing well.

Thanks in advance

Regards,

Srinivas
