Access via 'NULL' object reference not possible.

Hi,

I get the message: Access via 'NULL' object reference not possible.

IF NOT go_application->material->data-mara-matnr IS INITIAL.

.............

ENDIF.

How can I prevent this dump.

You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: " ").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.

1. As adviced earlier, use SEARCH before posting the query.

2. Post the query in right forum. this should go under ABAP OBJECT.

Hi,

Check the initiality ( if that objec is not iniital) of that object before assinging to antther...

so that we can avoid dump.

Thanks!

this didn't work.

IF NOT go_application->material->data-mara-matnr IS INITIAL.

Amit Khare seems to be very experienced, maybe he has the answer for my question.

Instead to say all over the time SEARCH

go_application is always not initial but I have solved the prbl.

IF NOT go_application->material IS INITIAL.

Well, this appears to have been moved. Where did you originally post it?

It was originally posted in general. I moved it. I was tempted to post it in "reject"...
