D365 - How to solve warning "[BPUnusedStrFmtArgument]:The placeholder '%1' to strFmt is not used in the format string."

Old migrated code from AX 2012:

warning( strFmt( "@cieb:cieb4", _sParamName ) );

shows this warning (in label is this value "Attention - parameter %1 not found."): BP Rule: [BPUnusedStrFmtArgument]:The placeholder '%1' to strFmt is not used in the format string.

 For this warning removing add literalStr() for label string validation.

warning( strFmt( literalStr("@cieb:cieb4"), _sParamName ) );
