Hi Friends,

I want to extract material data with the FM above.

But I get a short dump like this.

Error analysis

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', was

not caught and

therefore caused a runtime error.

The reason for the exception is:

The call to the function module "BAPI_MATERIAL_GET_ALL" is incorrect:

In the function module interface, you can specify only

fields of a specific type and length under "CLIENTDATA".

Although the currently specified field

"DOWN_CLIENTDATA" is the correct type, its length is incorrect.

the code is as follow.
