Looping issue in Smartform

[Former Member]

While activating the form, i came across a error called "A line of I_ITEMS and WA_ITEMS is not mutually convertible. In Unicode program, I_ITEMS must have same structure layout". But in program, i have defined both objects as follows..

Data: i_items TYPE STANDARD TABLE of ty_items.

Data: wa_items TYPE ty_items.

How to resolve this issue..

In Form Interface->Tables you need to give the declaration as itab like structure_name

If you are passing internal table from your program,it's struture should exist in ABAP dictionary.Even if you defined in your program,that is not sufficient.

If you are on NON-UNICODE system, uncheck the check box "Unicode Check active" from the attributes of the program. This will resolve your problem.
