Updating screen field values

[Former Member]

Hi All,

I want a field called status on my screen, once i select that field to 'yes' i want to automatically set a date field on the screen to today's date.

I want this to happen even before the PAI event, i.e., when i change a value on one field i want to trigger the action of updating another field.

is there a way to do this???

Thanks & Regards,

Hi,

Use FM DYNP_UPDATE_FIELDS.

Hi Thirumal,

YOu may have to use DYNP_VALUES_READ and DYNP_VALUE_UPDATE function modules in PBO section.

Hi Both,

I am working on this function module already, but what i found in library is this :"There are also two function modules - DYNP_VALUES_READ and DYNP_VALUES_UPDATE - that can read the values of screen fields and return values to them during the POV event"

So does this mean that only on POV this is used or if it can solve my case can anyone tell me the logic

I don't think ther is any problem in using these Fms in other places.

DYNP_VALUES_READ would give the values of the screen fields and DYNP_VALUES_UPDATE would update the screen fields with the values you pass.

There are examples given in the FM documentation also.
