Serial Number generation in multi-occ forms
I have three forms (form type 3) multi-occ with view fields, I want to generate serial number for records...based on step_no value.
step_no is a variable having step number from a table.
how to do validations on multi-occ forms...
i.e, whenever user goes to serial number field, first time it will be from table value...say 1,
he goes to next record, it will become 1+step_no = 2 like that..
but when user presses shift+tab key to go back from next field to serial number field, it should not increment...
all i want is : proper validations on generated serial numbers in multi-occ form...
can anyone help ?!
