New Deadline for Payroll Batch Loader 20D Nov 2020

Oracle has also provided a help document for this transition on the DOC ID
Transitioning from Payroll Batch Loader to HCM Data Loader: Overview (Doc ID 2557156.1)

PBL was mainly used to load the payroll data into cloud. Now Oracle suggests these approaches post PBL withdrawal:

• Incoming files in an HDL format. You can present data in HDL format and load them using HDL. In this case, no transformation is required. 
• Data loaded using HSDL. You can use user-defined spreadsheet templates to load data using HCM Spreadsheet Loader (HSDL). 
• File in a PBL format is converted into HDL format. You can use the HDL transformation formula to convert the PBL file into an HDL format. For sample transformation Fast Formula, see the Cloud Customer Connect forum Payroll Batch Loader (PBL) Conversion to HCM Data Loader (HDL) https://cloudcustomerconnect.oracle.com/posts/0e99071068 

Some Excerpts from the DOC ID:

Why is PBL decommissioned? 
HCM Data Loader (HDL) is the recommended mechanism for moving and synchronizing large volumes of data between systems. To avoid confusion and additional complexity in our data loading model, we have chosen to consolidate all our data loading tools.

When is the end of life for PBL?
For customers using environments provisioned on 19C and later, Payroll Batch Loader (PBL) is not available and HCM Data Loader (HDL) is the only method for loading payroll business objects into Oracle HCM Cloud. For existing customers, Oracle will now be decommissioning PBL in 20D. You will no longer be able to use PBL for data conversion or integration after 20C.

I am an existing customer whose environments had been provisioned in 19B and I then purchased a new environment.Will PBL be disabled on my new environment? 
In environments provisioned on 19C and later, PBL is disabled. If you complete an environment refresh, the newly provisioned environment will take on the behaviour of the source environment i.e. if the source environment has PBL enabled on it, then the target environment will also have PBL enabled on it

Do we need to create new Fast Formula transformation for HDL?
Yes. You are able to use the same logic as the PBL Fast Formula, but you will need to change the output to be the correct attributes and in the structure HDL requires

Does HDL do validations similar to PBL?
For example, does HDL validate balance loads and their feeds? Yes. HDL performs the same validation as PBL.

Can HDL support CSV based input files? 
Yes. In HDL, the default delimiter that separates values is a pipe character, because it is rare that a value would include a pipe. However, you can override the delimiter and use a comma instead by adding a SET command at the top of the HDL file.

Is there a limit on the number of rows we can upload?
Yes, there is a limit of 19,999 rows in any one upload. I am not too clear on this limit of 19999 rows.. Will have to test and see if it’s the number of lines on the input file or the HDL file.

Currently, PBL supports a wide range of entities, such as element entries, payroll balance conversion, and so on. Is PBL being deprecated only for element entries? 
PBL will be depreciated for all objects.

Mapping of the PBL task Names to HDL Business Objects:

Tip: DO NOT WAIT till the end of 20D to move your PBL integrations into HDL. If you are using PBL to load any payroll objects, then try to load those objects using HDL from now on. You will face some issues with HDL at the beginning however by the PBL is decommissioned, you will be in better shape.
