how to display values in multiple rows in a single row and column?

Rephrasing the question(since Rini is not having Access to Upload pictures)

There is a report called Consolidated Tracker which has the column ToolsAccelerator.
Currently, the report looks like this

If there are 2 values of ToolsAccelerators, 2 rows are created.
But, If there are 2 or more values, we need them to be displayed in the Same row and column. separated by commas.Like this:

The ToolsAccelerator column is filled with entries that are fetched from a column called LITERAL_NAME which is present in a table called T11_1.

Table T11_1:

The Project Detail ID in the consolidated tracker is fetched from column REFERENCE_ID from a table called T2.

Table T2:

For every Reference _id in T2, there is a corresponding Request_ID in T2.

The ToolsAccelerator value is fetched after the following conditions:
1. Request_ID of T2= REQUEST_ID of table T11

Table T11:

2. value in the Name column of T11 table is 'com.ibm.gbs.workitem.attribute.custom.ToolsAcceleratorsEnumerationList'

3. T11.VAL is equal to CONCAT(CONCAT('%|',T11_1.EXTERNAL_ID), '|%')

(Table T11_1 and T11 are displayed above)

4.T11_1.PROJECT_ID=T2.PROJECT_ID

After all this, the corresponding values of T11_1 table's LITERAL_NAME column is fetched.(in other words, ToolsAccelerator values are fetched)

Left Join statements are used to check the above conditions:

We have tried to use Listagg function, but did not get the correct output.Probably because of incorrect implementation.
Kindly advice how to implement this. Any suggestion would be appreciated.
Thank you.
