Hi,

I am doing sales order type validation, sales order distributionchannel combination validation i am performing if there no combination i am throughing an error message so that user can change the distribution channel but the fields are greyed out for input . i used chain and enchain for getting rid of this error but still its not working

Thanks in advance,

Are you doing it in a exit or BADI , and what kind of Message you are throwing...!

it is a custom module pool screen , with screen parameters as sales order type ,distribution channel ,storage location i am doing validation on these three parameters using chain and endchain i am througing error message when the above screen parameters mismatch

Hi

See there are 2 scenarios u will handle .

1. Validation on inputs made on screen

2. Greying out input fields for making change only in distribution channel ,on occurence of error.

For 1, Make use of event PAI.do take of help of flag variable (char 1)

For 2 Make use of event PBO.

This Flag variable will be used in PAI event once error messg triggered.this value of flag variable could be used in PBO for screen change.

Hope this helps.

Hi Eric ,

Whenever we show the error message , its the property associated with it that , it will gray out all the input fields , so in your case what you can do is

1. Either show the warning message so that you can still be able to input the new values in fields

2. Or if it is not possible to use any other type type of error other that the ERROR then you can make use of Chain End-chain. It will resolve your problem.

Hi Eric ,

It should work,

Refer to the links below , it will help

Meanwhile I am writing a code to see why is it not working for you.

Also see where have you written a chain End chain .. PBO ? PAI ? Let us know the code you have written.

Hi uma,

In

Chain

Field field-name module check

endchain

in the module i am validating sales order type , distribution channel , storage location etc , for each combition i am using one error message . should i keep each field in chain and endchain.

Thanks in advance,

Hi ,

Yes you should keep all the fields in chain end chain who you want to get enabled for input again.

Are you writing this logic in PAI ?

You can do a F1 in chain end chain for exact syntax .
