Validation rules

37 rules, as counted from the BOT's published material. They are written for people to read; software cannot run them as published. Source

How they are written: Written rules in BOT's documents, in Thai and English: a 'Validation Rule' column for each data element in Data File Manual version 3.1 (non-resident lending/borrowing data) (53 rows with a rule, in 6 tables); numbered rules in Validation7, 21-28 of Validation worksheet version 3.1 (non-resident lending/borrowing data) (1 ids); numbered rules in Possible value Validation of Validation worksheet version 3.1 (non-resident lending/borrowing data) (36 ids); numbered rules in ETL of Validation worksheet version 3.1 (non-resident lending/borrowing data) (1 ids)..

BOT publishes no XML schema file or rule file that software can run as published. BOT's Data Set page describes three automated checks its DMS system runs on every submission: Basic Validation, Complex Validation (relationships within the same data set, run on data received by 17:00 each day) and Cross Validation (between data sets, with results shown to the reporting firm the next day).

The rules, on bot.or.th

Counts are in the BOT's own unit, so they are not comparable with other regulators' counts.
