How length of variable is interpreted in visual studio CIL

Posted on by Dinesh Udhayan R

Hi,

I have an case, where an AIF service is consumed and the variable length is 20.

Through code i am concatenating two values, and assigning to a variable with length 20.

Consider an scenario, where the concatenation exceeds the length of 20. Ax is smart enough to truncate the values to length to 20.

But when AIF service is consuming the code, the length is not truncate the value. Tried debugging through Visual studio and found the variable does not have any length restriction on visual studio code.

Anyone experienced something similar. If so, could someone explain what is different and how to avoid this issue.

Highly appreciate any thoughts on this behavior. Thanks in advance.

Assuming that youre taling about strings, what you see is the documented behavior. Let me quote the documentation:

The System.String type in .NET Framework does not have a property that corresponds to the maximum length of an X++ str, and string truncation does not occur.

You can use functions like subStr() to take first 20 characters from a string.

Have you tried using a temp variable (System.String etc.)?
