How to move all fields data of structure or work area into one string ?

Hi All,

I am working on ECC 6.0.

I have a requirement to pass complete work area data into one field of type C length 322...

In SAP 4.7 we can simply Move wa_data to String.. But in ECC it gives error " Source and destination are not mutually convertible. In Unicode program must have same structure.

If any one is aware about this problem, please guide..

Thanks in advance..
