3) I'm using the std screen areas CTD & CTS with the std inputs available. As raised issue to SAP, they suggested me to re-input the data once again into the fields available & I did that. but nothing seems to be going in my way.
For this you can see that from your screenshot, that field labels are missing in table, you need to manually reselect them, that's the reason you get not_found, its a known SAP issue.
ie this is through transport as explained above in target system You can also add them through select fields in table customization
Can you try to import the transport again but make sure that
orginals" in the OPTIONS tab is selected?
The solution is to write down all the
technical field-names from view groups CTS and CTD in table TPT_FIELD_S
EL_C, then use the config area to select the fields properly. This over
writes the TPT_FIELD_SEL_C table entries with ones that have the "tabnam
e" populated! The application will now work as expected.
Also Please refer this :
Please try producing a new transport of the entire table TPT_FIELD_SEL_C
as R3TR TABU with appropriate key and transport to yor system, you
should choose to overwrite the destination table. Please let us know
the result after.
ie
Transactrion SE01
Select create a the workbench request.
then doble click into the request
and push the button Display/Change
Enter here the entry "R3TR TABU TPT_FIELD_SEL_C"
Push enter
Then one icon with a Key appear
Push the key and enter * for all the table entries or select the
each one that you need.
