screen field value

Former Member — Mon, 25 Jun 2007 10:08:02 GMT

Dear ALL,

We have added a new field to the existing transaction using a screen exit and provided the screen field with some validations.

When ever the user enter a rong value its throwing a message and coming back to the same screen... and the value in that particular field is getting erased.

i want the field value to be present , so that user can correct it.

can any body pls advice..

Regards,

Sandeep.

hi,

try to hold that value in a variable before throwing a message in PAI event, then in the pbo event replace the value of that field with the value of this variable.
