selection screen field validation

Former Member — Wed, 17 Oct 2007 14:52:34 GMT

Hi,

Is there any automic field validation way in which i dont' need to write the code at selection screen event in selection screen report.

e.g vendor name.

at selection screen, I have to check form lfa1 that wheher this record which user enters exits in lfa1 or not.

Is there any automatic way, in which i dont need to write the validation code for every selection field.

Thanks,

i don't think so automatic validation....except for few fileds like date where it checks for format and in case of select-options it checks if low value is not exceeding high value.....for others u need to explicitly do validation in at selection-screen event.

I believe that you can do this sort of thing with a foriegn key relationship in the ABAP dictionary, but not for fields like "Vendor Name". It is more geared toward codes rather than free text.

Hi,

While declaring the fields you need to specify the Dictionary varianbles, if that field is having F4 help then the field will be automaically validated with the respective data, if the field doen't have the F4 help then you need to write the code to validate it

There is no provision in SAP to validate values automatically except you provide search help for all parameters and all parameters are mandatory. This way you might be able to validate some parameters but i doubt it will take care of all your selection screen elements.
