IT 0016 issue

Dear Gurus.

As per client requirement .

i have configured 15 days Np in table V_T547T & T7INZ3 table...N...tested required scenarios everything was perfect.

Now in quality when we are testing system throwing error called  """Entry  E 06 does not exist in T7INZ4 (check entry)"""

****in IT 0016 dropdown also unable to find the 15 NP which we configured***** but tables updated as required( V_T547T & T7INZ3)

Note : in SE11 table we didnt make anu changes in the dev system.

Please suggest someone what needs to be done to move forawrd
