How To Fix BRAIN569 - Illegal operands in inverse formula &2

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN -

• Message number: 569

• Message text: Illegal operands in inverse formula &2

What causes this issue?

The definition of inverse formula '&V2&' can only use operands from the
formula group for input-ready formula '&V1&'. The formula group consists
of all operands from the input-ready formula, and the input-ready
formula (the carrier) itself.
'&V3&' is not contained in the formula group or is the only operand used
in formula '&V2&'. In the latter case use '&V1&' instead.

System Response

The query is malformed and cannot be generated.

How to fix this error?

In inverse formulas, only use operands from the formula group. Form the
inverse formula by breaking down the input-ready formula after the
operand to be inverted.
