Dear Expert,

Error when converting a constant amount MAXBT in T511P

CONVERT_TO_LOCAL_CURRENCY has been Called

Data used:

Validity end date: 28.02.2014

Constant: MAXBT

T511P Currency MOP

Currency of payroll driver HKD

Therefor, do the checking on OE00 and check the currency and validity dates for MOP currency.

Also, checked table V_T001 table the currency that assigned for the company code.

Checked the MOP currency and ISO code in V_TCURC table. And checked ISO code in V_CURC  table as well.

Still encounter error as above, appreciate you advice.

Thanks,
