DP91 - Split Dynamic Line Items based on week

Hi Gurus,

Need help on below requirement

Its more about split billing during the week…  Say for a  month 3 weeks values(Hours) are available , then the DP91 should create DMR with 3 line items for each week .

Currently the system is working fine for different month , say two months posting is there then DP91 is creating DMR  with two line items for each month , I want same to happen for week also.

Could anyone suggest me any solutions for handling this ,  Actually I am an abaper. I have tried with BADI's and User Exits to achieve this ,it is not working.

Is there any Specific BADI's to be used ?

Any configuration have to be maintained or OSS Notes to be implemented?

Thanks & Regards,
