Consider the following scenario:
In a multiform application, the user started in FormA.

1. From FormA, the user invoked FormB using CALL_FORM.
2. From FormB, the user invoked FormC using OPEN_FORM.
3. From FormC, the user invoked FormD using OPEN_FORM.
4. From FormB, the user invoked FormE using CALL_FORM.

There is an additional form in the application, called FormF. Which statement is true?

A. FormF can be invoked from FormC using CALL_FORM.
B. FormF can be invoked from FormA using OPEN_FORM.
C. FormF can be invoked from FormD using CALL_FORM.
D. FormF can be invoked from FormE using CALL_FORM.
E. FormF can be invoked from FormB using OPEN_FORM.

Answer: D

I don't know why. Could anyone help me?

I would have expected A, C, and D to be correct. However, I have NEVER set up an application of this configuration. Perhaps the forms C and D become 'blocked' when control is passed from B to E and now only form E is active. As I said, I have never given my users such a potentially confusing structure. Give it a go. Create five forms and see what happens, then get back to us.
