Do you really want to truncate the contents of the newly created 3rd field if input field 2 contains more than 47 characters?

Why is the 2nd awk script in your pipeline looking for the currency values in field 3 when the currency values, if present, will be in field 4 by then?

Please explain exactly what the format is for the "decimal" and "decimal & Currency" strings. Will that field always be empty if a monetary amount is not present? Do there really have to be at least two digits in a monetary amount? Should a decimal point be required in a monetary amount? If a decimal point is present in a monetary amount, should there be a required number of decimal digits after that decimal point? Are there minimum and maximum numbers of uppercase letters in a currency code?

- i dont want to truncate. i didn't get logic so i mentioned values explicitely.

- "decimal" have two decimal points. "decimal & Currency" have two decimal points and two uppercase alphabets.

Would
Code:
awk -F\| '
        {sub (/^[0-9][0-9] [A-Z][A-Z][A-Z]/, "&|", $2)
         sub (/[0-9.]*[0-9][A-Z]* *$/, "|&", $2)
        }

' OFS="|" file
1|22 JAN| Minimum Bal |20.00 | SAT
2|09 FEB| Extract bal |168.00BR | REM
3|MIN BAL | LEX

come close to what you need?

Your sample data also has a leading <space> and a trailing <space> around the monetary value. Are they supposed to be there or not?

records of kind 3rd row should be below: (Blank if No date & Month; Blank if no decimal at the end of 2nd field of input file)
Code:
3||MIN BAL|| LEX

---------- Post updated at 06:49 AM ---------- Previous update was at 05:57 AM ----------

Hi Don, Leading and trailing spaces are not necessary..

How about
Code:
awk -F\| '
        {if (!sub (/^[0-9][0-9] [A-Z][A-Z][A-Z]/, "&|", $2)) $2 = FS $2
         if (!sub (/[0-9.]*[0-9][A-Z]* *$/, "|&", $2)) $2 = $2 FS
        }

' OFS="|" file
