Hi Pranav,
Based on your information, I got that you need to pay all vendor invoices which were posting in 30.04.2015. The due date is independent (it is not relevant).
So, your F110 parameters are not 100% correct. There are several ways to paid only the documents which have posting date 30.04.2015. One of the easiest is the following below:
1. In your proposal, change value for the field "Docs entered up" from 30.04.2015 to 31.07.2015.
2. In "Free Selection", choose the filter BKPF-BUDAT and put the value 30.04.2015.
3. Run the proposal.
Important: be careful on comparing the proposal list with FBL1N list. The field "Open at key date" is NOT the same of "Docs entered up". In this case, you need to run FBL1N using the field "Posting Date" as filter.
Thank you!
