A nested function is a function encapsulated within another function. In CPMSAP Process Mining by Celonis , nested functions are a powerful tool for applying formatting in higher granularity. Nested functions will mostly appear when using conditional formatting.
By encapsulating several IF functions an arbitrary level of granularity, based on a series of test conditions that can either be true or false, can be achieved for formatting text output. The nested IF function can either be placed within the “then_value” or the “otherwise_value” parameter of the parent IF function. If nested functions are used, the system will enter the first IF function and check if the condition given within the first parameter is true or false. Depending on the result, either the “then_vaule” or “otherwise_value” parameter will be considered next. If the parameter contains another IF function, the system will again first check if the condition within the first parameter is true or false and then switch to the “then_vaule” or “otherwise_value” parameter. If that parameter as well contains another IF function, the circle begins again.
