Hello,
How many times have you seen a BW table, with its typical lenght and slashs, and you have not been able to identify which object represents? It looks difficult, but it isn't at all.
This is a short blog, for BW starters, and especially for any other consultant that, at any moment, need to know what represents a specific BW table.
It is easier than expected.
The beginning is common for all the tables, just a little difference between 0 and C.
Once you ignore this, you have just to focus in a letter. Knowing which represents this letter, you are a BW expert!
In the following lines I will show the difference between 0 and C, and possible letters that you will find.
Hope it is useful for you.
********************
For all BW objects this is the general naming convention:
* /BI0/Lxxx* - Standard
/BIC/Lxxx - Customer defined
where:
+ L+ - is the letter that will help us to distinguish quickly which kind of object is involved
+ xxx+ –is the name of the object. But it is important to know that:
- If object is a NON standard object then name will be just xxx
Now, let’s see how we can do the differentiation just based in the first letter after the /BI

In dimension tables L* is a character that represents each dimension. Possible values for L are:
- P is the package dimension of a content cube
- U is the unit dimension of a content cube
- T is the time dimension of a content cube
- I is the user defined dimension of a content cube
