Hi,
In my pgm i have coded such that
1)If the PO number is entered then the details of the corresponding vendor should be dispalyed.
2)If PO number not entered based on the vendor entered the details should be displayed
This is working fine..Now the problem is if the PO number is entered and if its not in the range of vendors given as the input the an error message should be displayed.Can use the function module ME_EKKO_SINGLE_READ in this case..Can anyone tell how to code?
