This step validates input column data as a bank account number used in the Czech republic (and Slovakia). Numbers in this format consist of three parts: prefix, base and bank ID. The step first trashes characters in the input that cannot occur in the bank number and saves them to the trashed output. Then, it tries to determine the bankId, base and prefix parts of the account number. According to the bank account format specification, the prefix and base must pass the mod11 test to be considered as valid. The step also supports output data formatting as specified by the property outputFormat and configurable invalid data handling as defined in the invalid data handling configuration properties. See the description of each property for more details. If the output is not processed by invalid data handling routines, the output format determines what will be written out:

• If there is an outputFormat defined, it is used to format the parsed data and the formatted data are written out. If the corresponding part of the outputFormat could not be determined, the empty string value is used instead.
• If no outputFormat is defined, the original value is written to the output.

If the bankIdOut output that has no relevant input:

• the empty value is written out if bank id was not recognized
• the standardized bank id is written out if it was recognized
