Error when Posting to Accounting

Question

dear SAP Gurus,
I have one inquiry about the posting.
I have created the posting run to Accounting using the Tcode PRFI or PRRW (create posting run), which is successful. But when I tried to post it to Accounting using Tcode PRRW, I encountered error as follow:
A RW609 Error in document: TRAVL 0000000215 ECDCLNT110
A F5152 Document number 3100 100000004 2009 was already assigned
Posting run 0000000227 could not be posted
in the posting run management, it shows the message "Document transfer has failed".
It is strange that previously I didn't encounter any problem, and it works fine in other clients. The problem exists in sandbox, which was no problem before, and I don't think that I change some customizing for travel expense.
Does it have anything to do with change in FI customizing? Would you please show me where can I locate the problem and solve it?
Many thanks before for the kind answer
cheers

hi,
see the condition record of mwst thru vk11.
see tha customer master and material master what y have mentioned as output tax. it should be as 1 = liable for tax.
see whether u have maintained the mwst in the pricing procedure.
