If its not giving an error it might just take a wile? Might help to aggregate or at least filter the output/component. Im also wondering about the { and } notation, fur us (CPM 4.5 on premise) we need to use around table and column names.

You need to use the STR_TO_INT() function to convert the values to Integers rather than String values. You cannot do mathematical calculations on strings.

When I put this formule, ive no result, the column become empty. Why ? STR_TO_INT(TMP_CDHDR_CDPOS.VALUE_OLD).

Hi Audrey, the STR_TO_INT function returns null, if the input is not a number. My solution for that would also to cast the numbers which are loaded as strings with the STR_TO_INT function so that they can substracted. Best, Viana
