awk script to append suffix to column when column has duplicated values
Please help me to get required output for both scenario 1 and scenario 2 and need separate code for both scenario 1 and scenario 2

Scenario 1
i need to do below changes only when column1 is CR and column3 has duplicates rows/values. This inputfile can contain 100 of this duplicated rows of column3 Value in column 3 to be suffixe with sequence starting from "a" followed by CR.
if we have appended suffix till a to z with CR like(aCR, bCR, cCR till zCR), then next suffix will be aaCR, abCR, acCR ans so on for column3

Input File

Code:
a||c
CR||2157237496
CR||2157237496
CR||2157237496
INV||2157237496
RNV||3457634589

Output File

Code:
a||c
CR||2157237496aCR
CR||2157237496bCR
CR||2157237496cCR
INV||2157237496
RNV||3457634589

Scenario 2 Required separate code for this scenario Below is for different file i need to do below changes only when column1 is DR and column3 has duplicates rows/values.
Value in column 3 to be suffixe with sequence starting from "a" except for first document followed by DR.
if we have appended suffix till a to z with DR like(aDR, bDR, cDR till zDR), then next suffix will be aaDR, abDR, acDR ans so on for column3

Input File

Code:
a||c
DR||3770022521
DR||3770022521
DR||3770022521
INV||9876543738

output file

a||c
Code:
DR||3770022521
DR||3770022521aDR
DR||3770022521bDR
INV||9876543738

I tried below code, it is giving me output for scenario 2 but not able to append sequence number to column3. I am able to suffix only "a" which is static. Here need to consider column1 equal to CR for scenario 1 and DR for scenario2 as well(that im unable to do)

Code:
awk -F"|" -v OFS="|" '{if(++a[$3]>1)$3=$3"a"}1' d1.txt

Code output :

Code:
a||c
CR||2157237496
CR||2157237496a
CR||2157237496a
INV||2157237496a
RNV||3457634589

Please help me to get required output for both scenario 1 and scenario 2 and need separate code for both scenario 1 and scenario 2

locale::codes::langext

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
