Hi,

Try using Dynamic creation of data object, like this:

DATA: dref TYPE REF TO DATA,

tdata TYPE string.

FIELD-SYMBOLS: <f> TYPE any.

tdata = 'CHAR_10'.

CREATE DATA dref TYPE (tdata).

ASSIGN dref->* TO <f>.

Then you can use <f> like data object of type 'CHAR_10'

Alejandro.

First, where is the 'CHAR_10' coming from? Is this a valid data element or domain in your SAP system? If so you can hit against tables DD04L and DD01L to get the data type.

CHAR_10 is neither a domain nor a data element in my system. So where is it coming from. If it does not exist in the system, I guess the incoming string would have to be a certain format, meaning tha the data type would always be on the left of the _ and the length would be on the right. If that is the case, you can simply do something like this.

report zrich_0001.

data: xchar_type(1) type c.
data: xlength(3) type c.
data: xstring(20) type c value 'CHAR_10'.
data: dataref type ref to data.

split xstring at '_' into xchar_type xlength.

create data dataref type (xchar_type) length xlength.

check sy-subrc  = 0.
