Parameters

Former Member — Tue, 19 Jun 2007 09:21:37 GMT

Hi,

I want to put a parameter for entering the file path, in the Selection Screen dynamically. If the user will enter a wrong file path, it should throw error.

I hope, this can be done through the use of RLGRAP structure.

Can anybody drop me a piece of code for doing the same in my S. Screen.

Thanks

Sangram
