So far I covered overall process flow (Part I), pre-requisites (Part II), step 1 (Part III) and steps 2 to 4 (Part IV). Now, lets discuss more on the configuration and customization aspects in this and upcoming blog posts, before we eventually come to step 5. I shall try to cover each element in as much detail as I can, based on what I have experienced working in a live multi-tenant implementation environment. I shall restrict to only those which I've actively worked upon, and there could be more which might be relevant for your specific case. Moreover, SAP might finetune some of these in the future, and hence, you should refer to SAP's latest documentation or support notes to validate if what I mention here is still applicable.

As earlier, re-sharing the overall process flow from Part I for easy reference.

Focus Area: PERNR Mapping Table: HRSFEC_D_EEKEYMP

This table is to map the different person identification elements in EC to PERNR in ECP. Do pause here, and check the SAP KBA 2493579 to learn about these EC elements.

Fields of the PERNR Mapping Table:

  1. Employee ID: From EC. E.g., 00ABE6F19F134430B8352D280080A641

  2. Employment ID: From EC. E.g., 6130

  3. Work Agreement ID: Usually hire or termination date in YYYYMMDD format. E.g., 20200608

  4. Personnel Number: PERNR. E.g., 1001234.

  5. Company Code: BUKRS. E.g., 1000.

  6. External Employee ID: From EC. E.g., 1001234. (As mentioned in earlier blog post, this shall likely be same as PERNR, unless you have a cross-company employee.)

  7. User ID: From EC. E.g., 1001234. Usually, this is the EC field you shall map to PERNR in ECP.

  8. Internal Person ID of an Employee: PERSON_ID_INTERNAL field in EC. E.g., 6102

If the replication program while processing an employee's data received in the EC query response is unable to locate an entry in this table, it considers that this as a fresh hire and shall make an entry for it in the table at the end of a successful replication.
Tip 1: As part of conversions load, if you had migrated historical infotype records from legacy on-premise HCM system into EC Payroll using an HR Data Cloning Utility (such as, NEXUS Suite by TIK as was done in my project), you would have to also load the key mapping table for all of these legacy PERNRs before you switch on the replications. If you don't, employee replication will result in these errors: Person already hired (PG 002) or External PERNR &1 is already hired. Please check longtext. (HRSFEC_SERVICES 285).

To upload data to this PERNR Mapping Table as part of conversion load, SAP has provided utility program: RP_HRSFEC_UPLOAD_EEKEY_MAPPING. It accepts a .csv file (or with any other column separator character, such as pipe) and with column order sequence matching the field structure mentioned above, except for "1. Employee ID" and "8. Internal Person ID of an Employee", which for some unfathomable reason are flipped in the acceptable input file format.
Tip 2: You may request your EC team to build a report in EC, or have CPI team build an integration iFlow to query EC and generate the above data as a file, with an additional Payroll Area column. Payroll Area addition would come handy, as ECP shall go live by pay area and you would want to limit your PERNR Mapping Table uploads to only the go-live population. You may enter any date for Work Agreement ID for your initial load (e.g., 19000101) without having to determine the true hire or termination date.


Focus Area: PERNR-specific Full Transmission Start Date: HRSFEC_PN_FTSD

By default, employee data is replicated from EC to ECP onwards from FTSD of the Config ID under which the employee belongs to. It's configured in table T77SFEC_PTP_CONF which we covered in Part III. Since Config ID is by payroll area, you can quickly make out the default FTSD for the employee. In our example, for an employee who is currently on A1 payroll area, her FTSD would be 6/10/2020.

Now there are situations when you want to deviate from this date:

  1. This PERNR was in withdrawn status at go live, aka "converted term", and was loaded with minimal information into EC. You don't want this data to land into ECP and overwrite good infotype data that you migrated from the legacy on-premise HCM system. The "converted term" would then be loaded under pay area XX (non-pay) in EC, which we don't replicate into ECP.

    When this PERNR is rehired in EC sometime in the future, you want the data replication to start from this rehire date onwards. That's when you shall maintain table HRSFEC_PN_FTSD for this PERNR with the Rehire Date as the PERNR-specific FTSD. You can optionally (and preferable for business user) automate this by implementing the BADI HRSFEC_B_CE_DECIDE_HIRE_REHIRE (available under Enhancement Spot HRSFEC_CE_MASTER_DATA_REPL) to plug the PERNR-specific FTSD record as on initial rehire events of "converted terms".

    * LOGIC:
    * 1. Processing is only for rehire scenario.
    * 2. Confirm that the employee is first time rehire of a converted term.
    * 3. Set the PERNR's FTSD as the job information start date.

    NOTE: The above sample code makes use of a custom class ZCL_HRSFEC_CE_ITMAP_HELPER. I shall share more about this class in a future post. This class will have static data as well as static methods to buffer and extract relevant configuration table entries for the concerned T77SFEC_PTP_CONF Config ID under execution.

  2. Another reason why you might need to make entry to PERNR-specific FTSD table (HRSFEC_PN_FTSD) would be because data in EC isn't suitable for successful replication until a later date. E.g., retro-effective changes to EC data which unfortunately can't be replicated into ECP without errors. We are talking of bad data scenarios, which do happen in the real world. So, you then come up with a date from when you want the data to replicate, and accordingly have EC portlet record start dates aligned to that date. This would be on a case-by-case basis, and hence not something you can automate via a BADI.

I shall cover more such interesting customization aspects in upcoming blog posts. Stay tuned. Until then 'Sarve janah sukhino bhavantu, samasta sanmangalani santu’ (Let all beings be happy. Let all beings be comfortable.).
