Hi Natalija,
The only conditional operator supported is ternary operator:
EXPRESSION or FACTOR=LogicalTest ? ExpressionIfTrue : ExpressionIfFalse
Like:
*REC(EXPRESSION=%VALUE%>0 ? %VALUE%*2 : 0)
If current value greater then zero then write current value multiplied by 2, else - write zero.
Fob BPC NW 10 with ABAP calculation engine nested ternary operator is not supported, with JAVASCRIPT calculation engine - nested is supported.
