Hi NB,
Try to find rounding flag in following BOP exits and see if this resolves your issue,
EXIT_/SAPAPO/SAPLBOP_FILT_010
EXIT_/SAPAPO/SAPLBOP_SORT_020
EXIT_/SAPAPO/SAPLBOP_000
EXIT_/SAPAPO/SAPLBOP_051
EXIT_/SAPAPO/SAPLBOP_052
EXIT_/SAPAPO/SAPLBOP_060
EXIT_/SAPAPO/SAPLBOP_069
EXIT_/SAPAPO/SAPLBOP_100
This seems to be some work, but this is the only way here.
