If the file contains 3 transactions for currency USD, 2 transactions for currency GBP and 1 transaction for currency INR ( in a single batch)
The BTL91 file generated for this example should contain three records of type 31, one each for USD,GBP and INR with the total transaction amounts for each currency.

Issue:
File generated from SAP program SAPFPAYM (T-code: FBPM) carries multiple record type 31 for same currency
For example: 2 records with USD, 2 records with GBP and 1 with INR for the example used above

Solution:
The issue of multiple records type 31 is caused due to a program error while generating the DME/PMW file
It can be rectified by the applying SAP Note 1136370 - DMEE PAYM: REGUH-SRTF1 is wrongly filled
Even after implementation of the above note, the problem may persist for the payment runs for which DME file has already been generated incorrectly. This is due to the fact that sort data for such payment runs is already stored in the system. To rectify such cases user may execute the program RFPAYM_RESET for these payment run to resent the payment medium information.
