In this article we will look into how the HDL Transformation Formula works along with a sample usecase to load Element Entry object..

If you haven’t checked the previous article on basics of Transformation formula, please check it out.

This is a guest post by my friend Sainath Reddy who writes Fusion related content on his blog https://oraclecloudhcmtechfunc.blogspot.com/. He has written some great content on both technical and functional side. Have a look at them.

If we have the input data in flat files i.e text, csv, dat etc., and then if we have to load that data into Fusion system then we need to use the HDL FF which converts the flat file into HDL format and then loads it into Fusion.

Now let’s look at the building blocks of HDL Transformation Formula before jumping on to how we do it.

Building Blocks for HDL Transformation Formula:

Building Blocks for HDL Transformation Formula are:
Input Variables
Return Statements

Input Variables available in HDL FF:

OPERATION, FileName, FileDiscriminator, LINENO and LINEREPEATNO are Input Variables available for this formula type.
Depending on the input file we need to add the extra input variables POSITION1, POSITION2, …, POSITIONn one for each input column.

Example:

E509|GRADE_CHANGE|2019/12/08|G1
E512|GRADE_CHANGE|2020/11/10|G2

Now, we will look at how these variables are defined in FF and what’s the significance of them.

  1. OPERATION
  2. FileName
  3. FileDiscriminator
  4. LINENO
  5. LINEREPEATNO

1. Operation:

This is a seeded variable provided by Oracle. Even PBL FF used to have this variable. The valid values for this variable OPERATION that we can use are:

FILETYPE,DELIMITER,READ,MAP,NUMBEROFBUSINESSOBJECTS,METADATALINEINFORMATION

  • FILETYPE –> OUTPUTVALUE –> DELIMITED

For FILETYPE Operation output value is DELIMITED

  • DELIMITER –> OUTPUTVALUE –>   |

For DELIMITER Operation output value is |

If we are using the comma separated flat file then use ‘,’.

Note: By default it is ‘|’

  • READ –> OUTPUTVALUE –> NONE

For READ Operation output value is NONE

  • MAP –> Business Object Attributes –> returns the business object attributes

For MAP Operation output value is the business object attributes

  • NUMBEROFBUSINESSOBJECTS –> OUTPUTVALUE –>Ex: 1

For NUMBEROFBUSINESSOBJECTS Operation output value is 1

In Flat file if we need to create the 2 business objects then give this as 2.

  • METADATALINEINFORMATION –> METADATAn –> Ex:METADATA1

For METADATALINEINFORMATION Operation output value is METADATAn

If we need the two METADATA’s then we have to create METADATA1,METADATA2

2. FileName: Business object file Name

3. FileDiscriminator: Business Object file discriminator

4. LINENO : It gives the which number.

5.LINEREPEAT And LINEREPEATNO: When we want to process the same line for multiple times then we will use these.

Example:
FileName = ‘ElementEntry’
FileDiscriminator = ‘ElementEntryValue’
BusinessOperation = ‘MERGE’

LINEREPEAT allows a single line of input to be processed multiple times. If it is ‘Y’ then one more time it will be processed. If it is ‘N’ then it stops processing that particular line.

LINEREPEATNO indicates the number of repetitions.If a line in a file is processing first time it will be ‘1’. And if the same line processing second time it is ‘2’.

BusinessOperation :  This is used for MERGE/DELETE/COMMENT operations to be performed in HDL.

Example:

IF LINEREPEATNO=1 THEN
(
BUSINESSOPERATION='MERGE'
BUSINESSOBJECT='ELEMENT ENTRY'
FILENAME = 'ELEMENTENTRY'
FILEDISCRIMINATOR ='ELEMENTENTRY'
LINEREPEAT = 'Y'
RETURN BUSINESSOPERATION,FILEDISCRIMINATOR,FILENAME
)
ELSE
(
BUSINESSOPERATION='MERGE'
BUSINESSOBJECT='ELEMENT ENTRY VALUE'
FILENAME = 'ELEMENTENTRY'
FILEDISCRIMINATOR = 'ELEMENTENTRY'
LINEREPEAT = 'N'
RETURN BUSINESSOPERATION,FILEDISCRIMINATOR,FILENAME
)

If the Element entry details and Element entry value details both are stored in the same line, then we need to process the same line twice. So LINEREPEAT is ‘Y’ for Element Entry and ‘N’ for Element Entry Value.  If ‘Y’ is there it will process the same line again, for ‘N’ it will go to the next line after it process that line.

Return values for this Formula type:

RETURN BusinessOperation, FileName, FileDiscriminator, Attribute1, Attribute2, …, Attributen

Mapping for Source Keys:

Syntax for PersonId(SourceSystemId) :  “PersonId(SourceSystemId)”= POSITIONn

Ex: “PersonId(SourceSystemId)”= POSITION21

Return values for Source Keys example:

RETURN BusinessOperation,FileName,FileDiscriminator,Attribute1,…,”PersonId(SourceSystemId)”,…,Attribute25
“PersonId(SourceSystemId)” Should be in double quotes

Roles and Privileges required to use HDL FF:

The privileges that are required to access:
Submit payroll flow – PAY_SUBMIT_PAYROLL_FLOW_PRIV
Load data from File – HRC_LOAD_HCM_DATA_PRIV

Human Capital Management Integration Specialist role is required for checklists, Data Exchange and to load data from a file flow pattern.

Enabling the File Encryption:

If the input file is encrypted, then follow the below process to setup the encryption setting. If input file is not encrypted also, check this setting once to ensure it is having NONE value.

Before loading the encrypted file, ensure the parameter is set in payroll process configuration.

My Client Groups > Quick actions > Payroll > Payroll Process Configuration

Manage Payroll Process Configuration task

In Default Groups > Select the parameter > Payroll Batch Loader Encryption Type Valid Values are PGPSIGNED, PGPUNSIGNED and PGPX509UNSIGNED. Default No encryption.

Complete Process to for HDL Transformation Formula:

  1. Create and Upload the flat file into content server manually or by using web services.
  2. Create the HDL Transformation Formula for HCM Data Loader.
  3. Run the Load Data from file payroll flow manually or using webservices.

Create Input File and upload to UCM:

Sample Input File:
E509|GRADE_CHANGE|2019/12/08|G1
E510|GRADE_CHANGE|2019/12/10|G2

Upload file to content Server from Navigator >Tools > File Import and Export

image 9 - How HDL Transformation Formula works with ElementEntry Sample
Tools > File Import and Export

Click add > upload the input file and select account as hcm/dataloader/import  > save and close

image 81 - How HDL Transformation Formula works with ElementEntry Sample
Upload input file

It generates the Content ID which we will use it while submitting the payroll flow. Keep a note of it.

Create a Fast Formula of type HCM Data Loader:

Navigate to > Setup and Maintenance > Fast Formula > Create New formula > Select type HCM Data Loader

Run the Load Data from File Flow:

If you are on Classic UI, Navigate to Payroll > Payroll checklist > submit a payroll flow > select Load data from file

If you have enabled RUI, the navigation would be

My Client Groups > Payroll > Submit Flows > select Load data from file

Submitting flow

Provide the Content Id and the Transformation Fast Formula from the above steps

image 84 - How HDL Transformation Formula works with ElementEntry Sample
Inputs to Flow

Once the process runs to success, you can check the HDL file it has generated from File Import and Export

image 85 - How HDL Transformation Formula works with ElementEntry Sample

The generated file will look like:

image 86 - How HDL Transformation Formula works with ElementEntry Sample

Generated HDL file
METADATA|ElementEntry|EffectiveStartDate|MultipleEntryCount|AssignmentNumber|CreatorType|ElementName|LegislativeDataGroupName|EntryType
MERGE|ElementEntry|2019/12/08|1|E509|H|ABC Element Name|IN Legislative Data Group|E
MERGE|ElementEntry|2019/12/10|1|E510|H|ABC Element Name|IN Legislative Data Group|E
METADATA|ElementEntryValue|LegislativeDataGroupName|EffectiveStartDate|EffectiveEndDate|ElementName|MultipleEntryCount|AssignmentNumber|InputValueName|ScreenEntryValue|EntryType
MERGE|ElementEntryValue|IN Legislative Data Group|2019/12/08|4712/12/31|ABC Element Name|1|E509|test|Grade Change|E
MERGE|ElementEntryValue|IN Legislative Data Group|2019/12/10|4712/12/31|ABC Element Name|1|E510|test|Grade Change|E

Now, let’s check the status of the HDL process on Data Exchange > Import and Load data screen.
