# MRV Document Operations For a demo example of following steps, here is the policy timestamp: **1675164736.675731674** ### **Task Summary** There are two roles: ‘**User*****’*** and ***‘*****Approver*****’***. *User* can create projects and send project definition documents to the selected *Approvers*. After the approval, *User* can add MRV reports to the project. On the basis of this documents the policy will be minting tokens into the account configured in the project. ### **Preparation** 1. Create 2 roles ‘**User*****’*** and ‘**Approver*****’*** and the corresponding containers (See example 1 for the more detailed description of how to work with roles)

2. Create all needed document schemas: 2.1 Schema for ‘**User*****’*** containing the fields: **First name**, **Last name** 2.2 Schema for ‘**Approver*****’*** containing the fields: **First name**, **Last name** 2.3 Schema for ’**Project**’ containing the fields: **Project name**, **Account ID** In order to mint tokens into another account (not into the account of the minting user) setup the required field

2.4 Schema for ’**Report**’ containing the following fields: **Start Date, End Date, Amount** (Please see example 2 *for the more detailed description of how to work with Documents*) 3. Add blocks for registering ‘**User*****’*** and ‘**Approver*****’*** into the containers created in the step 1 **Note:** it is important that DID of the user is used for ID of the documents as this value will be used further in the document for filtration

4. Add simplified grids for displaying Projects, Reports and Tokens

5. Create the token

### **Document Operations** #### 1. Project Definition **1.1 Create a project**

#### 1.2 Save the project

#### 1.3 Link to the token 1.3.1 Since another (not current user) account is used for minted tokens ’**tokenActionBlock**’ cannot be used, instead we will use ‘**tokenConfirmationBlock*****’***

1.3.2 To configure the target account for mixed tokens select ‘*Custom*’ value for ‘*Type*’ and the filed in the document from which to take the value for the Account ID (this field must have type: ‘**Account**’)

1.3.3 By default ’**tokenConfirmationBlock**’ does not have a link to the next block, thus it needs to be manually added

1.4 Add an approver as after the creation the project is not assigned to anyone 1.4.1 Add ’**interfaceActionBlock**’ wrapped into a container.

1.4.2 Select **Dropdown \_** value \*\*\*\* for **\_ Type**

1.4.3 Use system field **assignedTo** to filter documents based on users they are assigned to. Record value from **assignedTo \_** into\_ **Field** (This field will be changing our block)

1.4.4 Configure values from which fields from the document would be labels, and which ones would be values

1.4.5 Use ‘**documentsSourceAddon**’ for data for **Dropdown*****.***

1.4.6 Save the changed document

1.4.7 As ‘**documentsSourceAddon**’ does not have default events, we need manually add them.

1.4.8 Return to grid settings and add **Dropdown** into the target column.

1.5 Project Approval. Setting up the grid for project approvals. 1.5.1 To select only the projects assigned to the current Approver set the ‘**Assigned to User**’ flag

1.5.2 Add document approval block *(Please see* [*example 2*](https://docs.guardianservice.io/technical-information/library-of-policy-examples/data-input-via-forms-using-roles-to-partition-user-activities) *for the more detailed description of this workflow)*

1.5.3 Add Approve button into the grid

1.5.4 After the Approve, setup the KYC for the account connected to the project Use ‘**tokenActionBlock**’ with the appropriate settings

1.5.5 Configure the signing/verification of the document with the Approver signature by adding ‘**reassigningBlock**’. This block creates a copy of the source document and re-signs it with the key of the selected user.

1.5.6 Add Status attribute for easy filtering

#### 2. Report. To enable report creation only for approved projects, add create button into the grid selectively for documents with ‘Approved’ status 2.1 Add a ‘**documentsSourceAddon**' block to differentiate the documents on the basis of their status

2.2 Repeat the sequence for project creation to create the report {% hint style="info" %} **Note:** switch off ‘**Default Active**’ since create report button does not need to be an independent object {% endhint %}
