Trying to trigger error message on array element by using Error formula

Hello!

My name is Jarek Dorobek and I work for the University of Western Ontario Canada.

I am new at the absence management.

I'm trying to display an error message (should write to table PS_GP_MESSAGES) when the array lokup element returns zero rows.

I have created formula and added it to array element's Error Formula, but the message is not created.

The error formula looks like this:

Element Name: WHR ERR EMPL DATA

Formula text:

32000 >> SY[MSG SET NBR]

100 >> SY[MSG NBR]

EM[MSG PIN] >> FM[WHR ERR EMPL DATA]

My understanding is that this should work but it doesn't.
