Field validation in module pool program

[anand_n5]

Hi experts i have a problem in module pool program. I have created a screen with two fields and two function keys DISPLAY CREATE where i have to check these fields for validation.I know the syntax for field validation  (field<fld name> module<module name>) but the problem is i have to check both the fields for validation means if press display or create when both the fields are empty it should generate a massage that both fields are empty..please help me to solve this problem.

Use CHAIN ... ENDCHAIN in the PAI.

Hae you can do validation in PAI by placing those two fields in between CHAIN & ENDCHAIN .

Please refer the below screenshot for reference.

Hi anand,

It should be in PAI only which is meant for validation checks for the fields mentioned in Chain and enchain. That was the code I had written when I am doing a mini project at my learning stage. It is not at all required to mention in PBO.

IT SHOULD BE IN PAI MODULE ONLY.
