Purpose
The purpose of this document is to define the conversion approach to load Maintenance Plan Start object in order to Start the Maintenance Plans in S/4 HANA.
The purpose of the Maintenance Plan Start is to initiate the creation of Work Orders based on the criteria specified in the Maintenance Plans.
Maintenance Plans for Syensqo are defined with the purpose of:
- Preventive Plans - Used for Time Based and Condition based Preventive Maintenance with a defined Strategy
- Shutdown Plans - Shutdown Plans with a Defined Strategy
Conversion Scope
The conversion scope covers the approach for loading Maintenance Plan Start object in S/4 HANA system.
The data from legacy system includes:
- All relevant Maintenance Plans (MPLA.WARPL)
The data from legacy system excludes:
- Inactive Maintenance Plans ((System Status TJ02T-TXT04 = INAC)
- Maintenance Plans (MPLA.WARPL) to be Excluded (Exclusion List Mapping: EXC-Maintenance Plan Start) from getting started
List of source systems and approximate number of records
| Source | Scope | Source Approx No. of Records | Target System | Target Approx No. of Records |
|---|---|---|---|---|
| PF2, WP2 | Relevant Maintenance Plan for Maintenance Plan Start will be extracted from PF2 and WP2, excluding the records which require business decision, which include the following scenarios (not exhaustive):
| 70,000 | S/4 HANA | 70,000 |
| DCT | Maintenance Plan for Maintenance Plan Start for plants which do not have data existing from PF2 and WP2 | TBD | S/4HANA | TBD |
| DCT | Relevant Maintenance Plan for Maintenance Plan Start will be extracted from PF2 and WP2 which require business decision, which may fall under the following example scenarios (not exhaustive):
| TBD | S/4HANA | TBD |

|---|---|---|---|---|---|---|
| MHIS | WARPL | WARPL | Maintenance Plan Identifier | CHAR | 12 | Mandatory |
| MHIS | LRMDT | LRMDT | Date of Last Completion in Maintenance Plan | DATS | 8 | Conditional |

Data Cleansing
| ID | Criticality | Error Message/Report Description | Rule | Output | Source System |
|---|---|---|---|---|---|
| 9001-001 | C1 | Relevant and Active Maintenance Plan not scheduled until Business Continuity Cutoff Date. Set the Maintenance Plan to Inactive if not required to be started. | Business Continuity Cutoff Date is defined by parameter (MHIS-NPLDA). Based on all the relevant and active Maintenance Plans in MHIS table, identify what is the latest Plan Date (MHIS-NPLDA). If the date is before the Business Continuity Date parameter, this is an error. | Maintenance Plan, Latest Plan Date | PF2, WP2 |

Conversion Process
The high-level process is represented by the diagram below:
Data Privacy and Sensitivity
Extraction
- Syniti Migrate connects to the sources.
- An initial extract of the relevant Maintenance Plan Start data will be loaded into a google sheet report to assist business with any standardization.
Extraction Run Sheet
| Req # | Requirement Description | Team Responsible |
|---|---|---|
| 1 | Extract data from source system based on relevancy rule | SyWay Data Team |
| 2 | Google Sheet report pre-populated with PF2 and WP2 information to be generated based on relevancy criteria. | SyWay Data Team |

Transformation
The Target fields are mapped to the applicable Legacy field that will be its source, this is a 3-way activity involving the Business, Functional team and Data team. This identifies the transformation activity required to allow to make the data Target ready:
- Perform value mapping and data transformation rules.
- Legacy values are mapped to the to-be values (this could include a default value)
- Values are transformed according to the rules defined in
- Prepare target-ready data in the structure and format that is required for loading via prescribed Load Tool. This step also produces the load data ready for business to perform Pre-load Data Validation

Pre-Load Validation
Project Team
Completeness
| Task | Action |
|---|---|
| Verify Record Count | SyWay A2D Data Team to verify that the total number of relevant records from the DCT is equal to the total number of records in the Preload and Load Sheets. |
Accuracy
| Task | Action |
|---|---|
| Conversion Accuracy | SyWay A2D Data Team to verify that all fields below meet pass the checks:
|
| Review Error Reports | Review and correct the errors. Achieve a zero-error record count as much as possible. Raise defects for data remediated and requiring a correction in the source data. |
Business
Completeness
| Task | Action |
|---|---|
| Verify Record Count | Business Data Owner/s to verify that the total number of relevant records from the the DCT is equal to the total number of records in the Preload and Load Sheets. |
Accuracy
| Task | Action |
|---|---|
| Conversion Accuracy | Business Data Owner/s to verify that all the data in the load table/file is accurate as per endorsed transformation/mapping rules (and signed-off DCT data). |
Load
The load process includes:
- Execute the automated data load into target system using load tool or product the load file if the load must be done manually
- Once the data is loaded to the target system, it will be extracted and prepared for Post Load Data Validation
