Static ASSIGN with Offset Specification

Former Member — Tue, 02 Sep 2014 15:03:15 GMT

Hi,

While trying to work with field symbols using static ASSIGN and Offset/Length Specification, got the error as mentioned below.

So unless I mention the explicit length of the Offset or '*', I get the error. I was reading through the following link for some information & working through the code snippets when I ran into the issue,

https://help.sap.com/saphelp_nw04/helpdata/en/fc/eb38d5358411d1829f0000e829fbfe/content.htm

Any information on the same would be very helpful.

Thanks

You have to have it as follows:

FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
string1(10) VALUE '0123456789',
string2(10) VALUE 'abcdefghij',
END OF line.

WRITE / line-string1+5.
ASSIGN line-string1+5(5) TO <fs>.
WRITE / <fs>.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.

Thanks for the response.

I do not get any error when I mention specific length or '*' with the offset. The only problem is when you do not mention any length with the offset.

As per link below,

https://help.sap.com/saphelp_nw04/helpdata/en/fc/eb38d5358411d1829f0000e829fbfe/content.htm

Having WRITE after ASSIGN line-string1+5 TO <fs> should result in output, 56789abcde.

Explained as,

"In this example, you can see the difference between an offset specification in a WRITE statement and an offset specification in an ASSIGN statement. With WRITE, the output is truncated at the end of LINE-STRING1. Specifying an offset greater than 9 would lead to an error during the syntax check. In the first ASSIGN statement, the memory area of length 10 beginning with offset 5 in LINE-STRING1 is assigned to the field symbol <FS>. The output is meaningful because the memory area behind LINE-STRING1 belongs to LINE-STRING2. In the second ASSIGN statement, the length specification * prevents the system from addressing the memory area after LINE-STRING1."

So just trying to figure out if I am missing on something.
