Streamlining data entry: Exploring the new 'Paste' feature in Fiori Elements V4 tables

[fabio_b]

Introduction

Welcome to this blog! Today, we’re going to delve into an eagerly anticipated feature that’s been introduced in the recent release of SAP Fiori elements for OData V4: the ability to paste data into tables, much like you would in Microsoft Excel.

This enhancement significantly elevates the user experience for Fiori elements V4 application users.

Fiori elements V4 offers a variety of table types, each with different mechanisms for creating new rows. We’ll explore the availability and expected behavior of the “pasting” feature across each table type and creation mode. Stay tuned as we unpack this exciting development.

How to Select Cells in Fiori Elements Tables

Before diving into the new Pasting feature, let's refresh our memory on cell selection in Fiori Elements Tables.

Tables may have editable fields within their cells. When you select a cell, the editable field inside that cell automatically gains focus.

To avoid this, press the CTRL key (or Cmd⌘ Key on a Mac) before selecting a cell with your mouse.

A New Pasting Capability

Previously, the pasting feature was limited to the creation of new rows in tables, with no option to update existing cells. However, this has now changed.

This new mode, which necessitates cells selection, permits the updating of existing rows and the creation of new rows, depending on the chosen creation mode

Before we explore this new development, let’s revisit the types of tables available in Fiori elements V4 and the applicability of the new paste feature for each.

Fiori elements V4 offers four types of tables: grid tables, responsive tables, analytical tables, and tree tables. For more insights, you can refer to the SAPUI5 documentation).

Interestingly, the paste feature is only applicable to the grid tables and responsive tables.

Both grid tables and responsive tables offer three modes of creation:

1. Inline Creation mode
2. Empty Row mode
3. New Page mode

The new pasting feature can only create new rows when the Empty Row mode is activated. This setting can be configured in the application’s manifest file

For all other creation modes, the new pasting feature can only be used to update existing cells, not to add new rows.

Let's explore various scenarios.

⚠️    Note:

The success of these pasting operations depends on the compatibility of the data structure in the clipboard with the structure of the target table. If there are any discrepancies, you might need to adjust the data or the table structure accordingly.

Pasting Into a Grid Table

    Pasting a Dataset From One Cell

Imagine an application user who has a dataset copied to his clipboard.

This dataset could be anything from a simple list of numbers to a complex array of information.

The user then navigates to a Fiori elements table control. Instead of selecting multiple cells or an entire row or column, the user only selects one cell within the table.

This is where the magic happens. When the user pastes the data, the table selection automatically extends to include all the data from the clipboard. This means that even though the user only selected one cell, the entire dataset from the clipboard is pasted into the table. The starting point of this pasting operation is the cell selected within the table.

This feature can be incredibly useful for quickly populating a table with data, especially when dealing with large datasets. It allows the user to paste a large amount of data into a table with just a few clicks, saving time and effort.

    Pasting a Dataset Into a Selection Area Containing The Creation Row

When the user pastes a dataset into a selection area that contains a creation row, the system performs an update and insert operation simultaneously. This operation is particularly useful when the user wants to update existing records and add new ones at the same time.

Here’s what happens:

1. The system first identifies the cells in the selection area that exist before the creation row. It then updates these cells with the corresponding data from the clipboard.
2. After updating the existing rows, the system creates new rows with the remaining clipboard content.

 

    Pasting a Dataset From One Cell Above the Creation Row

This scenario is a amalgamation of the two previous scenarios we’ve discussed. Here, the user has a dataset in the clipboard and selects one cell. The destination area includes the creation row.

The process unfolds as follows:

1. The user selects a cell in the table which is located above the creation row.
2. The user then pastes the dataset from the clipboard. The pasted data is distributed in two ways:
        - The rows between the selected cell and the creation row are updated with the corresponding  data from the clipboard.
        - The remaining data from the clipboard is used to create new rows in the table.

This feature allows for a seamless integration of updating existing cells and creating new rows simultaneously. 

    Pasting a Dataset Into a Limited Selection Area

In the realm of data manipulation, one overlooked powerful feature is the ability to paste a dataset into a limited selection region. This process can be incredibly useful while working with large datasets when you want to update only a specific subset of cells.

Only the cells contained within your selection are updated. This means you have full control over which parts of your original data are modified. It’s a precise and efficient way to handle data updates, ensuring that the rest of your dataset remains untouched.

 

    Pasting a Short Dataset Into a Larger Selection Area

When you paste a short dataset into a larger selection region, the system performs a partial update operation. This operation is useful when you want to update a specific portion of your table without affecting the rest of the data.

Here’s what happens:

1. The system identifies the rows in the selection region that correspond to the data in the clipboard. It then updates these rows with the new data from the clipboard. 
2. The remaining rows in the selection area that do not have corresponding data in the clipboard are left unchanged.

 

Pasting Into a Responsive Table

In the context of pasting scenarios, the responsive table stands out with a particularity: the creation row is initially positioned at the top of the table. Interestingly, this position can change based on the user’s actions.

This distinctive characteristic leads to additional scenarios that we are about to delve into.

    Pasting a Dataset Into the Creation Row

Just like the grid table, the creation row also allows you to paste data directly into it. 

For the responsive table, the creation row is conveniently located at the top of the table. When you paste data into it, new rows are created right at the top. This means that the newly added data is immediately visible and accessible, without having to scroll down the table.

Here’s how it works:

1. Select a cell in the creation row
2. Paste your dataset using the paste icon
3.  As soon as you paste your data, new rows are instantly created at the top of the table. Each row of data you pasted becomes a new row in the table.
4. After the data has been pasted and the new rows have been created, a fresh creation row appears just below the inserted rows.

    Pasting a Dataset Into a Cell Above the Creation Row

In the previous scenario, we discussed how pasting data into the creation row creates new rows at the top of the table and moves the creation row to the middle of the table.
Now let's see what happens if the user paste a dataset into a cell above the creation row.

Here’s what happens:

1. The user selects a cell above the creation row and pastes data
2. The rows between the selected cell and the creation row are updated with the relevant data from your dataset.
3. If your clipboard content has more rows than there are between the selected cell and the creation row, the remaining rows of data lead to the creation of new rows in the table. These new rows are added just above the creation row.
4. After the data has been pasted, a fresh creation row appears below the new rows. This allows you to continue adding more data if needed.

This feature provides a flexible and efficient way to both update existing data and add new data. It ensures that your data remain organized and accessible, no matter where the Creation Row is located in the table.

Smart Pasting: The Challenge of Read-Only Cells

In Fiori elements V4, a new layer of complexity is introduced when dealing with read-only cells. These cells can be set to read-only due to various annotation configurations such as field controls, update restrictions, or insert restrictions. This means that not all cells are open for modification, adding a unique challenge when pasting data into tables.

The pasting feature in Fiori Elements V4 is designed to intelligently handle this complexity. It takes into account the particular state of each cell and respects the permissions set for it. If a cell is marked as read-only, the pasting feature will not attempt to update it, even if there is corresponding data in the clipboard. This ensures that the integrity and rules of the table are maintained, and no unauthorized changes are made.

This feature is particularly useful in scenarios where certain fields in a table are locked for editing to preserve the accuracy or consistency of data. Users can confidently paste their data, knowing that the pasting feature will only update the cells that are permitted to change.

⚠️    Note:

In addition to the checks done by Fiori element v4 during the paste, a strict backend validation is still needed to ensure data consistency

Conclusion

This new pasting feature that allows to both updating existing data and creating new onces has significantly enhanced user experience providing an Microsoft Excel like behavior.

It’s an exciting development that we look forward to seeing in action as more users adopt Fiori elements V4. Stay tuned for more updates and enhancements in future releases!
