Oracle - cumulative counts within chain of records
I have an oracle table DM_TEMP_SUMMING_DVC_BY_FW with below columns and sample data. Data below shows
-dmc_id ='408' there are 2109 devices which are having firmware_version='RT1' and it is the first firmware_version because image_prerequisite is null for this firmware_image.
-dmc_id ='408' there are 40 devices which are having firmware_version='RT2' moved from "RT1" and so on.
The requirement is to create the chain of firmware_versions and the count of devices moving through the chain. For example:
Firmware_version movement is RT1-->RT2-->RT3-->RT4
so the count of devices moved from RT1 to RT4 is (RT1+RT2+RT3+RT4)
count of devices moved from RT2 to RT4 is (RT2+RT3+RT4)
count of devices moved from RT3 to RT4 is (RT3+RT4)
count of devices at last firmware_version is RT4
Below is the input data in table DM_TEMP_SUMMING_DVC_BY_FW
+-----------+-------+-----------------+-----------------+------------------+-------------------+
device_count| dmc_id| firmware_version| cg_id |image_prerequisite| count_within_dmcid|

It looks like what you're missing is partitioning on the root firmware_version, which you can get by using connect_by_root(), like so:
WITH dm_temp_summing_dvc_by_fw AS (SELECT 40 device_count, 408 dmc_id, 'RT2' firmware_version, '0000' cg_id, 'RT1' image_prerequisite, 24028 count_within_dmcid FROM dual UNION ALL
SELECT 24 device_count, 408 dmc_id, 'RT3' firmware_version, '0000' cg_id, 'RT2' image_prerequisite, 24028 count_within_dmcid FROM dual UNION ALL
SELECT 18 device_count, 408 dmc_id, 'RT4' firmware_version, '0000' cg_id, 'RT3' image_prerequisite, 24028 count_within_dmcid FROM dual UNION ALL
SELECT 2109 device_count, 408 dmc_id, 'RT1' firmware_version, '0000' cg_id, NULL image_prerequisite, 24028 count_within_dmcid FROM dual UNION ALL
SELECT 1 device_count, 1422 dmc_id, 'RT1' firmware_version, '0000' cg_id, NULL image_prerequisite, 7 count_within_dmcid FROM dual UNION ALL

ETA:
With the additional requirement to handle cases where firmewares are at the same level as each other, I *think* this does what you're after:

What this latest query does is first find out if there are firmwares that are at the same level as each other, and if so, we listagg them together (here, I've used ~ as a separator for clarity in the results - there's nothing to stop you from using the same separator as you use in the sys_connect_by_path).
Once we have that, we can do the connect by, but we need to look at just the first entry in the newly calculated firmware column (otherwise we won't find a match in the image_prerequisite column). Then it's just calculating the results in the same way the previous query did.
