What causes this issue?

Table (or view) &V1& is used as the <DS:DE.SELMETHOD>selection
method</> in <DS:TX.DDDOK_SHLP_ELEMENTARY>elementary search help</>
&V3&. The search help has a <DS:TX.DDDOK_SHLP_PARAMETER>parameter</>
&V2& which is automatically filled with the field of the table (or
view) having the same name during the selection. You now want to delete
the field, whereby the parameter of the search help would lose its
meaning or at least change completely.

System Response

Deleting the field is not allowed or is allowed and causes a warning.

How to fix this error?

If you really want to delete the field, you should probably also delete
the parameter of the search help having the same name. Use the
maintenance transaction of the ABAP Dictionary for the particular
search help. Activate the table (or view) again if necessary.
