Error reading table

What causes this issue?

An entry with key &V2& is missing from table &V1&.

System Response

The entry is needed to delete entries from dependent tables.
Deletion is not possible without this entry.

How to fix this error?

Use transaction se16 to find out from table TMC1T the name of the
generated structure that you want to delete. The names of the generated
structures are in field GSTRU of table TMC1T. Choose the entry with the
description of the structure you are processing. Then maintain table
TMC4 so that MCINF = &V3& and GSTRU is the name of the generated
structure found in table TMC1T.
