I\'m running into that error when trying to insert any number except 0 into a field with format NUMBER (2,2).
UPDATE
PROG_OWN.PROG_TPORCENTAJE_MERMA
SET
You can't update with a number greater than 1 for datatype number(2,2) is because, the first parameter is the total number of digits in the number and the second one (.i.e 2 here) is the number of digits in decimal part. I guess you can insert or update data < 1. i.e. 0.12, 0.95 etc.
Please check NUMBER DATATYPE in NUMBER Datatype.
