### Problem description & analysis:

Here below is an annual and quarterly sales data table:

![r/esProc_Desktop - Calculate Using Adjacent Row/Interval When Data of The Same Group Is Continuous (Link Relative Ratio And YOY)](https://preview.redd.it/calculate-using-adjacent-row-interval-when-data-of-the-same-v0-ctorto6q4txd1.png?width=379&format=png&auto=webp&s=bf70514c45d62abb28b9755659950c0afbc49a3b align="left")

**Task**: Now we want to calculate LRR and YOY (to calculate in cell D1).

### Solution:

Use **SPL XLL** and the code is as follows:

|  | A |
| --- | --- |
| 1 | \=E(‘A1:C21’) |
| 2 | \=A1.(Sales-Sales\[-1\]) |
| 3 | \=A1.group(Year) |
| 4 | \=A3.(~.(Sales-A3.~[\-1](https://www.reddit.com/r/esProc_Desktop/submit/#).Sales)).conj() |
| 5 | return A2.new(~:LinkRelative,A4(#):YOY) |

**A2**: Calculate LRR, \[-1\] represents the previous row.  
**A3**: Group by Year.  
**A4**: Calculate YOY. The symbol ~ represents the current member in the loop function, and # represents the sequence number of the current member in the loop function.

The results are shown below:
