ECS Payment Run

We are implementing SAP in Bihar were-in the invoices that are sent to consumer conisits of 3 amounts. i.e

Eg:

Invoice Posting date

01.01.2016

16.01.2016  Due Date for PPI

26.01.2016 Due date + 10 days grace period

2400  To be paid within/upto due date to be eligible for PPI (16.01.2016)

2500 Actual Invoice amount (Upto due date + 10 days grace)

2600 Amount including DPS to be paid after due date + 10 days ( After 26.01.2016)

Now when we execute the ECS run through FPY1 Amount to the tune of Rs 2500 is credited as payment by ECS.

Is it possible to have an ECS run executed for Rs 1900? So that PPI to the tune of 100 can be credit.?
