Hi Bob,
S&OP supports all SAP TREX expressions. Unfortunately the TREX expressions wiki is not available externally.If you are SAP internal, you can access the TREX wiki for a list of supported TREX expressions that can be used in calculation expressions;
http://trexweb.wdf.sap.corp:1080/wiki/index.php/TrexExpressions
In general, the following are commonly used in configuration :
Operators : + - * / > < = > = <=
Conditions : IF ISNULL ABS OR AND NOT
Aggregation: SUM, AVG, MIN, MAX
There are plenty of examples in SAP delivered SAPMODEL1 which are sufficient for most projects.
We will document these and more in detail in the Model Help section.
Hope this helps.
Thanks,
Raghav
