Dear Nezwi: 
Thank you so much for your feedback, and nice to meet virtually 

To further clarify the first para of my post, this might be more applicable in organizations that has a separate software system designed specifically to identify the suppliers from all levels (outside and inside the country office) more likely the level of detail are high. For instance, in my organization the “E-Tendering” is an electronic event (above referenced as technology tool) that was developed recently to ensure the public bidding competitive process, carried out with fairness and transparency to ensure best value of money.  Basically, there is link between the internal system developed and the external process that utilizes the supply chain strategy for sourcing the suppliers, while the structural map increases to include second-tier suppliers and second-tier customers, as all involved in the flows of products, services, finances and information from original supplier to the end-customer, which might be followed differently in other institutions.
 
Given the supply chain mapping builds on the tools and techniques of process mapping, at the same time per the strategic function of the Organization, the process needs to be engaged in the early stages of project design once the buyer (supply chain unit) receives the prerequisites from the client, to ensure efficient delivery at place, lower risks and cost effective.
 
Furthermore, as you correctly mentioned the internal systems are utilized to monitor the activities upon awarding the contract and manage its performance with review and budget compliance.

Thank you again @Nzewi for your follow up response. I think we agree that the process mapping tracks and analyzes the steps of work activities and the people who are involved in carrying out each step, at the same time the process mapping as you mentioned looks at the sequence of steps and adjust by eliminating those are not needed or repetitive steps for better efficiency, in contrary the Supply chain mapping is cross-functional and inter-organizational system.
 
Where I come from, there is no specific recipe for success when compiling policies and processes but simply there are proven guidelines and special measures, that are followed by the functional units (teams/ departments) who are keeping the strong ties with the process steps to smoothly adapt with the fluid situation and ever-changing environment.  
 
Further to what you have quoted, my first para is modified in consistent to the rest content, also the term "buyer" refered by in the structure mapping of my organization stands for tier-1 customer, while the requesting unit that manages the supply activities and ensure the quality would be tier-2 customer, then the end-user client would be the tier-3 customer who also requested the goods and services from tier-2 customer at the first place, finally the services and goods distributed to the final recipient consumers/ beneficiaries of the acquired goods and service whom would be the tier-4 customer.

Hope this would sound more sense to you, 

Cheers!

I want to further contribute on the above discussion, the differences between process mappings and supply chain mapping
Though the word mapping is common to both, however, Processs mapping is the unique way of using diagrams (flow charts) to illustrate the flow of process from the most perspective (macro) to the level of details (micro) required to identify opportunities and for improvement.
The essence of this is to see the workability of a process and to establish the working boundaries and limits and to put in place checks in order to improve efficiency.
For example, the process of constructing a building, the process starts from the sub-structure (the unseen part of the building, which includes the foundation, which can be normal foundation, raft foundation or pile foundation depending on the soil texture and characteristics, the number of  floors and other parameters) to the super structure, the seen part, which includes the beams, the couloms, the block walls, this is further divided into sections, to the roofing and finally finishing of the building.  
To achieve this, a lot of team work, brainstorming, inputs, ideas, communication and proper documentation is put into action.
Supply chain mapping on the contrary is engaging across the suppliers and sub contractors engaged on the building construction to documents the exact source of every material, every equipment engaged in erecting the building, e.g Electrical Sub-contractor, it involves the total knowledge of all the electrical materials, fittings, pippings, equipment engaged, likewise for all other sub-contractors and supplier engaged in the construction of the building.

I would not go.
My decision is based on those that I come in contact with more than myself I am not a high risk person.  I would be very upset if I contracted the virus and infected someone else who became very ill.
