* add child doctype - Cash Flow Mapping Account

* adds new doctype - Cash Flow Mapping

* adds new doctype - Cash Flow Mapper

* adds new doctype Cash Flow Mapping Template

* adds new doctype Cash Flow Mapping Template

* adds adjustments to Cash Flow Mapper:
- remove fields from Cash Flow Mapping Template Details
- update in Cash FLow Mapper

* get cash_flow_accouts from Cash Flow Mapping

* change `tmp` to `mappers` and make sure `mappers` is sorted by its `position` field

* changes description from 'Net Profit/Loss' to 'Profit for the year'

* set `net_profit_loss` `parent_account` properly

* modify `get_account_type_based_data`:
- changed signature such that `account_type` parameter is now `account_name`
- where clause in query is now based on `name`

* remove zero rows

* de-duplicates row, summing similar accounts in the process

* makes gl sum calculation use `parent_account` as a condition

* add the `section_leader` immediately after adding net profit, sorts `accounts` by `is_working_capital` field

* adds `is_working_capital` to "account_types" so that we can use this to determine when to add "Changes in working capital" for operating activities

* add "Movement in working capital" subheader

* refactor code for readability

* adds new fields to `Cash Flow Mapping`:
- `is_interest_paid` to allow me recognise accounts for 'Interest Paid'
- `is_income_tax_paid` to allow me recognise accounts for 'Income Taxes Paid'

* allow `Cash Flow Mapping` to be renamable

* adds new field - `section_subtotal` useful for only Operating Activities

* changes `Cash Flow Mapping` doctype fields:
- remove `is_income_tax`_field
- add `is_income_tax_liability` field to identify tax payable accounts
- add `is_income_tax_expense` field to identify tax expense accounts in P or L

* calculates and shows tax paid adjustment in cash flow statement

* renames `is_interest_paid` to `is_finance_cost`

* - adds finance costs calculation
- correctly sets opening balance dates

* prevents users from selecting extra options in Cash Flow Mapping

* adds validation to prevent selecting multiple options

* adds new fields to Cash Flow Mapping

* calculate non cash p or l items (2nd pass)

* separates default cash flow generation from custom

* adds new setting to Accounts Settings:
- allow user elect to use customised cash flow report

* clean up

* removes mandatory constraint from accounts field

* allow rename, disallow create and delete

* adds patch to add default Cash Flow Mappers

* refactors custom_cashflow

* add article to explain configuration

* refactor

* further refactor

* final clean up (hopefully)

* clean up for codacy

* more codacy fixes

* more codacy fixes

+# How To Customise Cash Flow Report
+
+As your chart of accounts begins to get more complex and reporting standards change and evolve, the default cash flow 
+report might no longer suffice. This is because ERPNext might not be able to accurately guess the classification and 
+purpose of all accounts in the charts of accounts. Another gripe you might have is the inability to adjust the report 
+format to fit your needs.
+
+This will no longer be a problem because ERPNext now allows users to customise the cash flow report.
+
+
+## Technical Overview
+Customisation is made possible by the introduction of two new doctypes - Cash Flow Mapper and Cash Flow Mapping. Both 
+doctypes contain the information required to generate a cash flow report.
+
+Cash Flow Mapping shows how accounts in your charts of accounts map to a line item in your cash flow report while 
+Cash Flow Mapper gets all the Cash Flow Mappings that relate to the three sections of a cash flow statement.
+
+With this, you generate detailed cash flow reports to your requirements. This might not make a lot of sense but it will 
+after we go through an example.
+
+## Example
+### Background information
+Let's assume we have a fictitious company for which we want to generate a cash flow report.
+This is what the cash flow report looks like at the moment:
+<img alt="Default cash flow report" class="screenshot" src="{{docs_base_url}}/assets/img/articles/default-cash-flow-report.png">
+
+We don't like the report for the following reasons:
+- The reporting format is too scant.
+- The 'Net Cash From Operations' figure is wrong
+
+### Customisation Process
+
+We wants the Cash Flow Report to look something similar to the format in the images below:
+<img alt="cash flow format 1" class="screenshot" src="{{docs_base_url}}/assets/img/articles/format-1.png">
+<img alt="cash flow format 1" class="screenshot" src="{{docs_base_url}}/assets/img/articles/format-2.png">
+
+#### Activate Customised Cash Flow Report
+Do this in Accounts Settings by checking the 'Use Custom Cash Flow Format' checkbox. This will cause ERPNext to only 
+use your custom format for cash flow reports.
+
+After doing that, your cash flow report should look like this:
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/no-mappers.png">
+
+Move to the next section to build the report.
+
+#### Create Cash Flow Mappings
+For each line, we need to create a Cash Flow Mapping document to represent it.
+
+<img alt="new cash flow mapping form" class="screenshot" src="{{docs_base_url}}/assets/img/articles/new-cash-flow-mapping.png">
+
+You can think of the Cash Flow Mapping as a representation of each line in the cash flow report. A Cash Flow Mapping 
+is a child of a Cash Flow Mapper which will be explained later. 
+
+Let's start by creating Cash Flow Mappings that will represent the add back of non cash expenses already recodgnised in
+the Profit or Loss statement. We want them to appear on the cash statement as:
+- Income taxes recognised in profit or loss
+- Finance costs recognised in profit or loss
+- Depreciation of non-current assets
+
+Start by opening a new Cash Flow Mapping form.
+
+The fields in the Cash Flow Mapping doctype are:
+- **Name**: This something to identify this document. Name it something related to the label
+- **Label**: This is what will show in the cash flow statement
+- **Accounts**: This table contains all the accounts which this line relates to.
+
+With this information, let's go ahead and create the Cash Flow Mapping Document for the line 'Income taxes recognised in profit or loss'
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-1.png">
+
+I have named it 'Income Tax Charge' and given it a label 'Income taxes recognised in profit or loss'. We want this 
+line to reflect income tax charges from our profit or loss statement. The account where this happens in our chart 
+of account is named 'Income Taxes' (an expense) so I have added 'Income Taxes' into the accounts table. If you have 
+more accounts representing income tax expenses, you should add all of them here.
+
+Because Income Tax expense needs to be adjusted further in the cash flow statement, check the 'Is Income Tax Expense' 
+checkbox. This is what will help ERPNext properly calculate the adjustments to be made.
+
+*For best results, let parent accounts have child accounts that have the same treatment for cash flow reporting 
+purposes because ERPNext will calculate net change of all children accounts in a situation where the selected account 
+is a parent account.* 
+
+In the same way, I have created for the remaining two mappings.
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-2.png">
+
+Finance costs also need to be adjusted so make sure to check the 'Is Finance Cost' checkbox.
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-3.png">
+
+Next let's add Cash Flow Mapping for items that show changes in working capital:
+- Increase/(decrease) in other liabilities
+- (Increase)/decrease in trade and other receivables
+- Increase/(decrease) in trade and other payables
+- VAT payable
+- (Increase)/decrease in inventory
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-4.png">
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-5.png">
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-6.png">
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-7.png">
+
+<img alt="custom cash flow statement" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-8.png">
+
+Don't forget to tell ERPNext that these mappings represent changes in working capital by checking the 'Is Working 
+Capital' checkbox.
+
+At this point we have created all the mappings necessary for the Operating Activities section of our cash flow 
+statement. However, ERPNext doesn't know that yet until we create Cash Flow Mapper documents. We'll create Cash Flow 
+Mapper documents next.
+
+
+#### Create Cash Flow Mappers
+Cash Flow Mappers represents the sections of the cash flow statement. A standard cash flow statement has only three 
+sections so when you view the Cash Flow Mapper list, you will that three have been created for you named:
+- Operating Activities
+- Financing Activities 
+- Investing Activities 
+
+You will not be able to add or remove any of them but they are editable and can be renamed.
+<img alt="cash flow mapper list" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapper-2.png">
+
+
+Open the Operating Activities Cash Flow Mapper so we can add the Cash Flow Mappings we have created.
+
+
+- **Section Name**: This is the heading of the section.
+- **Section Leader**: This is the first sub-header immediately after the profit figure. Relates only to Operating 
+Activities Cash Flow Mapper
+- **Section Subtotal**: This is the label for subtotal in the cash flow statement section. Relates only to Operating 
+Activities Cash Flow Mapper
+- **Section Footer**: This is the label for the total in the cash flow statement section.
+- **Mapping**: This table contains all the Cash Flow Mappings related to the Cash Flow Mapper.
+
+Now add all the Cash Flow Mappings you have created and Save. You should have something like this:
+<img alt="cash flow mapper for operating activities" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapper-4.png">
+
+ Refresh the cash flow statement and view the changes.
+<img alt="updated cash flow report" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapper-3.png">
+
+Looks close to our requirements but we are not done yet. Create new mappings for 'Investing Activities' and 'Financing 
+Activities' sections of the cash flow statement.
+
+<img alt="cash flow mapping" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-9.png">
+
+<img alt="cash flow mapping" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapping-10.png">
+
+<img alt="cash flow mapper for operating activities" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapper-5.png">
+
+<img alt="cash flow mapper for operating activities" class="screenshot" src="{{docs_base_url}}/assets/img/articles/cash-flow-mapper-6.png">
+
+Here's what our cash flow statement now looks like:
