Summary | The Time Of Of Training fields of Form R Part B had maximum limits set too low |
Impact | A PGDiT who had been on long term leave was unable to complete their Form R due to validation failures |
Non-technical Description
Each of the Time Out Of Training (TOOT) fields on the Form R Part B was limited to a maximum of 999 days.
A PGDiT who had been on long term leave had a total combined TOOT that exceeded that limit, the limit has been increased to 9999 days (approx. 27 years). This limit was chosen as it is not possible to identity a non-arbitrary four digit limit, but having some limit helps eliminate any obvious copy paste or other input errors.
Trigger
Validation on TOOT blocked Form R submission
Detection
PGDiT raised a support ticket
Resolution
The TOOT limits have been increase from three digits (999), to four digits (9999).

Root Cause(s)
Validation limits were set too low
Field validation guidance noted 999 days as a limit
It was believed to be enough
This amount of TOOT is an extreme outlier, out of over 74,000 submitted forms this is the first time that 999 days has not been enough

Lessons Learned
Outliers happen, but I feel be made the right choice at the time - given the data we had.
We should always be prepared to adapting as new data becomes available.
