SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_BRS - BRFplus Business Rule Services

• Message number: 201

• Message text: Call processing failed due to wrong parameter format

What causes this issue?

The system has tried to process a call to a BRFplus function in the
managed system. However, the parameters passed to the function do not
comply with the requirements set forth for parameter passing to BRFplus
functions.
For example, passing an amount parameter to BRFplus requires that the
amount is treated as one structure parameter with a value and a currency
field. In contrast to this, passing an amount parameter to an ABAP
Dictionary function is done using a separate value field and an amount
supplement on the same structure level.

System Response

The function cannot be called.

How to fix this error?

Make sure the parameters passed to a BRFplus function are compliant with
the formal requirements.

Procedure for System Administrators
